  • The things are not pondered over feature and functionalities of management software. It touches the only surface and you may end up with the wrong choice.
  • When it comes to deployment, it means not only having an ERP management platform but the right one. A software solution that addresses any challenges faced in your business processes.

RFID and IoT – A better vision for the Seafood Industry


  • Fish should smell fresh and mild, not sour or ammonia like,a fish’s eyes should be clear and shiny.The shrimp should not smell like bleach or ammonia, it indicates the growth of bacteria.And in the case of lobster,it should not be soft like cottage cheese or have a pungent odor. These are the basic tips that one should keep in mind while buying any seafood.But many people are unaware of these aspects and that leads to serious repercussions.

  • So here question arises why the freshness of seafood an important factor?The study estimates that approximately 55,000 cases are reported annually due to the illnesses — that are caused due to consumption of bad seafood .
  • In this article, we are going to review our creation on the RFID Technology. We have created the AI based Seafood supply chain ERP where the seafood supplier can track and trace the freshness and quality of seafood.


IoT Sensors :

We are using the IoT sensors for Water Quality and measurement of environmental conditions including temperature, Humidity, Air Flow etc. It will offer an instance alert on your mobile phone! 

Water quality sensors :

  • It monitors pH, temperature, NH3 and NH4 of the tanks where the seafood is stored.
  • It provides the facility to view the critical parameters of the water quality in real-time from your electronic device.
  • It is also equipped with the notification services that indicate when parameters are trending towards thresholds or breach parameters.

Environment sensors :

  • It offers real time temperature and humidity monitoring. 
  • Sensor being used in Cold chain logistics can offer real time monitoring & trace-ability. The temperatures in these transportation vehicles should be kept favorable according to the species.
  • It gives us the access to Dashboard to monitor these sensors. 


 Trace-ability through RFID technology : 


  • In this process, the harvester catches the seafood from the sea bed and brings it at dockside.
  • After reaching the dockside, the harvester puts all the species in the crates as per the capacity of a particular crate.
  • At the dockside, the harvester sells his catches to the sea food processing company through an agent (called as tagger) of the company itself.
  • The  RFID Tags are solely identified which allows to scan the items in a bulk quantity rather than each bar-code individually.
  • These RFID tags are placed on the crates at the dockside by the tagger.
  • The introduction of RFID tag eliminates the use of papers as the data is entered directly with the help of handheld devices.
  • The information is automatically uploaded to a cloud database. This means that workers in the head office have access to this information in real time and can plan accordingly for production and payroll functions.
  • The wireless printers are placed at the dock locations in order to print the receipt and the harvesters are on their way in just one click.

How to prove the freshness to Seafood?

  • The processor company can track the item’s check-in/check-out time and also can view the exact location of the item by entering the RFID code in the device.


Payroll and Accounting management :

  • In this user can manage the salary structure of the employees.
  • It refers to the administration of employees’ financial records including salaries,wages,bonuses,deductions and net pay.

Odoo studio Limitations

Odoo studio allows you to customize the user interface with very limited programming knowledge. It allows to write some Python code as well but a very limited portion of features can be customized from there. Here are the areas and industries where it will not work or somehow will create hurdles,

  • Nothing you do in odoo studio can be used in the community edition of odoo.
  • for all many enhancement to odoo 12, there are major weaknesses associated with recording custom odoo applications.
  • Because of the way you develop with odoo studio, it can again be very tough to control processes inside production installations.

Highly Customized business process

If your current business process if highly customized or proprietary to your owned business then generic ERP process may not work for you well and can turn into confusion for your employees.

Manufacturing Process

This is the main area where the Odoo studio will not work because of complicated processes. E.g. if you are looking to execute the work order in different stages and at the similar time you need some task order to go to the near stage after a real amount of time, it should be possible to customize

Import/Export of data

The migration will really not useful on this area, we have recently viewed an issue of importing work order and so the customer has had to change to the on-premise odoo
When you migrate from another system, your import process requires a high degree of customization and for that, you will need a full path to the Odoo backend system to write Python code.

Same way, you can not customize the export process very well.

Crons and Schedulers

Because you have restricted access to the Python//backend system, you can’t write crons very well and can’t automate many methods you want.

Ownership of the Data

The hosted answer limits the control of your data to the Odoo itself. However, they have a reliable cloud but if you want to keep the data completely, you will have to sort of premise Odoo that means, self-hosted Odoo. That doesn’t expect that you will have to choose some odoo partner to host your odoo on their support, you can have your private leased server from any provider and you can host it there.

At Silent Infotech we recommend going for either On-premise community or on-premise Enterprise. It’s a myth that it is hard to manage the on-premise odoo instance. We have Odoo special cloud and infrastructure in place to host on-premise odoo with the full power of customization.

How to use RFID for inventory & warehouse management

RFID stands on “Radiofrequency Identification”.

RFID is the technology which is working on radio frequency waves. So this technology is used to automatically identify the objects.

Here the objects could be anything, it could be a book in a library, any item which you are purchasing from the shopping mall, inventory in the warehouse, or maybe your own car. Not only objects it can be used to tracking the animals as well as the birds.

In this technology, the RFID tags used to get attached with the object which we want to track. This RFID reader is continuously sending the radio waves, so whenever the object is in the range of the reader then this RFID tag is used to transmit its feedback signal to the reader.

It is nearly similar the technology which is used in the barcode. But in case of a barcode, the object and the scanner should be in a line of sight. As in the RFID, technology is not a line of sight technology so far as this object is in within the range of the reader, the object is able to identify the reader and it is able to send a feedback signal back to the reader.

Using the RFID technology we can track the multiple objects at the same time.

RFID system contains 2 components,

  1. RFID reader
  2. RFID tag

RFID tags are coming in many ways,

  1. Active tags
  2. Passive Tags
  3. Semi-Passive Tags

If it is a mobile handled like we will be using today only a handled reader and an RFID tag will be needed.

RFID readers mainly consist of 3 components

  1. RF signal generator – It generates the radio wave which is transmitted using the antenna. Also, receive the feedback signal which is coming from the tag.
  2. Receiver / Signal Detector – To process the information which is being sent by the RFID tag.
  3. Microcontroller – many times this RFID reader is directly connected with the computer.

How to use RFID for inventory & warehouse management

  • Supplier reserve the products through the application for reservation.
  • Transfer through the system to the warehouse manager.
  • After agreeing the supplier’s warehousing application the warehouse manager chooses to confirm the expected storage.
  • Suppliers follow up the requirements, import the information by electronic tags and single phase correlation with shipments.
  • The staff collates the information of the goods ready for shipment through the vehicle read-write device.
  • The RFID reader installed at the door of the warehouse instantly reads out the goods and sends the information to the company.
  • Achieve real-time dynamic management of supplier’s shipment information and confirm shipment information again.

Warehousing Process

  • After goods enter the storage area, the staff scan the goods in the storage area.
  • If quantity and excepted quantity are kept, the next step will continue.
  • The system follows up stocks and supply information and lays down the location of goods.
  • And sends the information to the onboard computer to indicate the best path.
  • After the goods are mounted, scan the RFID labels on the track and check the cargo information.
  • Information has been associated with the shelves to completes the warehousing process, to achieve the synchronization of checking location.

Outbound process

  • After the delivery order is received by the information, it sends to the forklift truck.
  • After the goods are off the shelves, the staff scan the electronic labels on the shelves to unbind the goods with the shelves.
  • The staff scanned the goods in the shipment area and confirmed the shipment information.
  • When the goods are transported to the doorway of the warehouse, the RFID fixed reader on the door of the warehouse checks the cargo information and quantity again.
  • Completing the outgoing process after confirmation.

Inventory Process

  • First, the system sends the inventory plan to the PDA(Personal Digital Assistant) handset.
  • The staff can check the information about the goods by checking PDA.
  • After receiving the instruction, the staff scan all the goods by mobile mode.
  • Read all cargo information at one time.
  • Record the inventory results synchronously and compare with the inventory plan to achieve dynamic inventory.

Benefits of RFID

  • Allows individual stock items to be traced, located and retrieved without human intervention.
    • Because the RFID chip system monitors the stocks 24/7
  • Automatically identifies stock levels to check for when recording is required.
    • This is so that user time for manual recording can be reduced.
  • Provides more accurate system and eliminates human errors.
    • This is because the company will benefit from fewer errors in ordering costs and so save money.
  • Many RFID tags can be read at once
    • This saves time because of whole pallets of products can be checked simultaneously.
  • Tags can be overwritten – the information can be changed.
    • This enables to be updated, for example when the stock is moved from one side of a store to another.
  • Security of stock is increased.
    • This is because of tag readers can be placed at exits so that if stock if moved without authority it triggers the alarms.
  • It can help to save money.
    • This is because RFID tags can prevent over-stocking on items such as perishable goods that have a short shelf life.
  • RFID technology at the point-of-sale can be used to monitor demand trends.
    • This is so stores can use the information to predict what should be ordered or for similar products to be considered for sale.

Barcode Vs RFID

Barcode system requires a line of sight for a read.RFID system uses a radio wave proximity system.
Barcode reader typically operates in distance of 1 to approx 18 inches.RFID system can operate in distances greater than 100m.
Due to the line of sight requirement, barcode system can only read a single barcode at a time.RFID system depending on certain types and/or flavors of systems can read anywhere from 10’s to 100’s tags in simultaneously.
The quality of a barcode can deteriorate rapidly over a short amount of time resulting in failed read attempts.RFID tags are typically more rugged and therefore have a longer life expectancy than barcode labels.
Barcode readers are only able to read information from the barcode label.RFID system has the ability to read and write to the RFID tags.
Today barcodes are found on almost every item and there are no privacy issues involved with its use.RFID tags are more reusable and rugged as they are protected by a plastic cover.
Barcodes are a universal technology in that they are the norm for retail products; stores that own a barcode reader can process barcodes from anywhere in the world.RFID contain high levels of security; data can be encrypted, password protected or set to include a ‘kill’ feature to remove data permanently.

Silent Infotech’s Solution

Odoo Community VS Odoo Enterprise

In the starting phase, odoo familiar as OpenERP is a set of open source enterprise management applications.

The large companies, small business, associations and many different types of organizations used odoo for control, automate, measure and optimize their operations, finance and projects.

In the odoo version 6,7, & 8 there are no technical variations between community and enterprise version and it has changed in V9.

Features of Odoo Community:

The Odoo Community Association is the non-profitable organization which promotes the global use of odoo and assists the synergetic development of odoo feature.

It provides financial, organizational and legal assistance to the larger odoo open source community. It is also provided as an independent legal entity where community member can subscribe the code, funding, and other resources with knowledge and their subscription will be maintained for public benefits.

Odoo software can be used, modified and distributed by anyone.

The source code, bug reports pull requests are hosted by GitHub to access anyone.

Features of Odoo Enterprise:

If the user applies for the proprietary license he/she only can use the odoo enterprise subscription.

  • Modifications are allowed.
  • Distribution only to odoo enterprise subscribers.

All odoo projects are fully hosted on GitHub and access to all partners and customers who have an odoo subscription.

The whole database and back-end applications, without limitations, are in Odoo Community.

  • Basic Functionality is in Odoo Community.
  • Migration to the next version by Odoo SA engineers is in Odoo Enterprise.
  • Several Functionalities are in Odoo Enterprise.
  • Support of the non-customized Odoo Enterprise by Odoo SA Engineers.
  • Apps from Odoo Store.

Odoo Enterprise is a combination of “odoo community + additional functional modules”

The difference between two editions Community version &Enterprise version.

UniquenessCommunity edition does not contain all the features of the enterprise.Enterprise edition does contain all the features of the community.

Hardware & Scalability:

  • If we follow the hardware essence odoo can be estimated for companies of almost any size and odoo did it for 2000 global companies with vast terrestrial distribution but it recommended the breaking applications and database servers for 90 employees. The load balancing of application server would be used for a company who have 250+ employees.
  • There are 90% free and 10% paid applications are available in odoo app store.
  • Odoo Enterprise includes additional unique modules that will move the ERP experience to the next level.
  • Any localization can be installed as additional on both versions.

Flexibility in community and enterprise apps:

odoo have the modular structure, by this, you can customize through modules and database configuration.


Installing high availability Odoo 11 on ubuntu 16.04

You must be aware that now odoo has released version 11 officially. To know odoo 11 features click here

In this tutorial I’ll explain you how to install high availability odoo version 11(Community version) on ubuntu 16.04

Note : There is no major difference for installing odoo community and odoo enterprise version.

Overall System Architecture


If python is already installed, make sure you have installed python version 3.5 or above. Previous versions of python are not compatible with odoo 11.

Installation Guide

In this tutorial, I assume that you have properly configured your network for the required servers and you have basic networking knowledge to replace/change ip addresses mentioned throughout this tutorial with the appropriate ip addresses.

Database Server(s) Installation

Step 1 : Installation

Before you proceed for the installation, make sure you have configured locale settings properly.

sudo apt-get -y install postgresql postgresql-contrib

Step 2 : Create user with password

sudo -u postgres createuser odoo11
sudo -u postgres psql
psql=# alter user odoo11 with encrypted password '<password>';


Step 3 : Allow remote connection from application servers

All below lines in /etc/postgresql/9.5/main/pg_hba.conf file on top

host all odoo8 trust
host all odoo8 trust
host all odoo8 trust

This command will installed all the dependency libraries on the system.

Note : Debian package installer by default install postgresql as dependent package, we can stop the postgresql service and remove service from the system startup service list.

sudo systemctl stop postgresql
sudo update-rc.d postgresql disable

Step 3 : Database configurations

Let’s help application server to find the database from the configuration file. (/etc/odoo/openerp-server.conf)

db_host =
db_port = 5432
db_user = odoo11
db_password = xxxx

Note : Don’t forgot to replace your database name and database password with appropriate values.

Step 4 : Custom Modules

To install the custom modules on all application server, you need to configure NFS to share the directory which can be accessible from all the application and which should be mounted automatically on system startup.

After successful configuration of NFS on all application server you can add mount path in addons_path param(can be found on odoo configuration file)

Load Balancer Installation

Step 1 : Install nginx

sudo apt-get install nginx

Step 2 : Nginx site configuration

Create a configuration file under /etc/nginx/sites-enabled/xyz.com.conf with below content. Don’t forgot to change the domain name and SSL certificate path.

upstream backend  {

upstream backend-longpolling {
