Introduction:

I am not a person who has original ideas or a nature of observing things and environment to make them better. I thought that whatever needs to be invented is already done. I went on with certain ideas after exploring internet and looking around; asking friends and familiars.

Out of many Project Ideas that I thought of from Gas Sensors for Manual Scavangers, Digital Weighing Spoon, Digital Milk Can, Sound Pollution sensing and increasing the Traffic signaling timer to Goat Health Management System, I decided to pursue my Final Project on Weight Measurement and Management System for Goats (goat IT).

Reference Image from the referred Research Paper
Foreword:

My Project is Smart Goat Weight Measurement and Management System. I prefer to call it "GoatIT" - Application of (IT) Information Technology to measure and monitor the Weights of Goats with respect to FCR (Feed Conversion Ratio) / Link2 to manage the Growth and Profitability.
Body weight information of livestock animals is significant for trade, routine animal health monitoring and dosage calculations for treatment of diseases.
The answers to the following questions will give an indepth overview about my final project. I selected this project out of many Ideas that popped up due to certain reasons.
Vidarbha region of Maharashtra is known infamously for Farmer suicides due to scarce rains and inproductivity. An allied/supplementary business of Goat Farming could help them to sustain. Only thing is to do the Goat Farming scientifically.
The commercial weighing scales and machines available in the market are very costly. I wanted to bring the the price of these weighing balance in the grasp of the farmers.
Also, the data log on the server will notify the farmers about the options to sell or hold or pay attention to a particular goat (Doe or Buck).

WHY this Project?

Vidarbha region of Maharashtra is known for Farmer Suicides. This is because of reliance on only one source of income mainly farming which is affected by uncertainty of environmental conditions, diverse rain pattern - sometimes scarse or too much causing loss of crops.

Goat Farming is a lucrative option to supplement the agricultural farming and farmers of other regions (Marathwada, North Maharashtra) of Maharashtra are doing it profitably because of applying scientific methods like measurement of FCR, track of development and health by sensors, vaccination status etc.

Vigyan Ashram is also having the Goats and they provide Scientific Solutions directed towards the Rural Technology to the needy. They were already conducting certain experiments about the Nutrition, FCR (Feed Conversion Ratio), Data Maintenance for monitoring the Health Status, Pregnancy, Vaccination schedule, Weight Gain, Growth of the Goats in their Farm.

But, I noticed that the Weight is taken on Hanging Type of Weighing Balance and the Data is maintained in a Rough Notebook. They have enquired about the Balance and it was going to cost them 13,000 INR.

So, I decided to pursue this project. But, considering my competence in Mechatronics, I decided to limit my Final Project to building a Weighing Balance and maintaining the Weights of the Goats. Later, in the next spiral, other sensors like temperature, heartbeats and events like vaccination, pregnancy could be added.
Goat Farming business is growing because of various reasons–

What is FCR?

Reference: Animal Care Practice-Folio3

The amount of crops/feed that is required for the production of a unit of meat is known as Feed Conversion Ratio (FCRs) and they are discussed in the aspect of efficiency.

FCR is a mathematical relationship between the quantities of feed provided (fed) and the weight gained by consuming it. It can be calculated by dividing the total input of the given feed by the total weight gain.

F.C.R = Input of feed / Weight gained by the animal

The feed conversion ratio for goats On the high concentrated feed, goats have an average FCR of 4.5, 5.5 on good-quality forage. And on straw ration, 30. FCR tends to be higher for older lambs (e.g. 8 months) than younger lambs (e.g. 4 months).

Goat Weight Measurement and Management System (Goat IT):

"Goat is the Poor Man's Cow"

Problem Statement:

Goat Farming in many areas is unorganized. Goats are identified in a flock based on their color, horns, size etc. for recording (in a notebook manually) their weight, health status, nutrition, vaccination schedule, milk yield etc.

Issues-

  1. Weight could not be documented properly
  2. Goats cannot be differentiated and identified easily
  3. Still, the documentation is done in the notebooks manually.
  4. Farmers rely on their experience and extpertise to assume about the health status of the flock

Solution:

  1. My Goat Binder
  2. go360 Bio Track by Agsights are already available solutions in the American market.

My idea is to fabricate a System which would

Benefits:

Possible Difficulties:

Limitations:

I will restrict my fablab project to measuring the weight of the goats on daily basis and display it through a output device and simultaneously sending it to cloud.
In Spiral development, all the sensors may be joined and complete health data of goats can be maintained.

What will my Final Project "GoatIT" Do?

My project will be able to help Farmers in multitude of ways. The Flow of the activities in my project is as follows:

  1. The goats will have RFID tags attached to their necks through a band and the goats will be differentiated based on their RFID numbers
  2. The goats will approach the Weighing Balance placed at the entrance of their cage.
  3. The RFID tag reader will read the tag and send the information to the Server
  4. Goat will stand on the Weighing Balance
  5. Weight of the Goat will be displayed on the LCD screen attached to the scale/machine.
  6. The same weight of the Goat will be sent to the Server and entry would be done in the respective RFID number of the Goat.
  7. Thus, a data log would be created on the server for the weights of the goats.
  8. This data could be accessed by the farmers anytime and anywhere and used to make decisions about paying attention or holding or selling a particular goat.
  9. Basis being the FCR i.e Feed Conversion Ratio - which calculates the Weight gain by the Goats in relation to the quantity of the Feed Input. The weight of the goats increases on daily basis approximately 60 grams and more.
  10. This weight change could be monitored with the help of my project.

The result of the animal weighing is displayed on the LCD screen and sent to the RFID-based database identification system. Reference / Link2

Who has done what beforehand?

I surfed a lot through google, YouTube, ResearchGate and other platforms to find about Smart Goat Weight Measurement Scale but couldnt find enough references.
Most of the research was on finding the weight of the goat by measuring the size of the girth, length of the goat etc.
Commercial weighing Machines have been made by many and suppliers could also be found on IndiaMart.
One of the Research Papers that I found was having the detailed documentation of Iot Weigh Scale machine for Cattles / Livestock. The Research Paper could be found here.

Few IoT projects done by the Makers Community are-

  1. Smart Weighing Machine for Remote Weight Measurement and Monitoring on IoT Design Pro Website
  2. Weight scale IoT by ESP32 on GitHub
  3. IoT Weight Logging Scale by SFUPTOWNMAKER on SparkFun
  4. Digital Scale With ESP32 by Fernando Koyanagi in CircuitsMicrocontrollers on Instructables
  5. IoT Cat Litter Box on Instructables by Igor Fonseca Albuquerque

One of the websites with intensive information about esp32 and IoT is The Internet of Things with esp32 Created by Espressif Systems. Many Projects, Tutorials, Introduction and exploring could be done by referring these resources.

Any Project comprises of the Designing, Assembly, Tests-Trials and Final Application Demonstration

ESP32 uC PinOuts:

I was confused about the Pins on which the sensors needed to be attached. Also, I was unable to understand the types of communication protocols. So, I referred this pinout and default pins used by others to make the connections.

PCB Design:

The Heart of the Project which senses and actuates the whole system is the Sensors, MicroController and the Output devices.
The Final Project PCB was designed by me in the Input Devices Week.

The details about the two Sensors RFID Tag Reader (MFRC522) and Load Cell (HX711) used in the Final Project could be found in the Week 10/Assignment 11 of Input Devices.

Problem:

This Board was functional till the Interfacing and Applications Programming Week, but later on it stopped working. I checked the continuity between the Pins and the Sensors. It was OK. But, after connecting again, the Voltage Regulator became very Hot. I disconnected the Power supply at once but Alas! the MicroController Chip was fried. Ichecked the continuity and it showed continuity between the 3V3 and GND. I felt devastated.

We tried to figure out the reason for the mishap. Even the Board of my Colleague - Anand Tale got fried. We thought that the Volatge Regulator might have malfunctioned and hence the 5V supply might have fried the ESP32.
I then desoldered the ESP32 and soldered the new ESP32 chip over the PCB. It worked well for few days and then the same problem happened with me and Anand.

The Older PCB was looking Bad due to heating by Hot Air Gun used for desoldering and so, I designed the New PCB with seperate 5V supply for LCD display (as it required repetetively adjusting the Contrast by turning the Blue colored knob on the Back side of I2C module) and HX711.

Laser Cutting:

Details about Laser Cutting could be found in the Week3/Assignment 4 of Computer Controlled Cutting. I have used the Laser Cutter for cutting the PressFit assembly Casing designed for the Final Project Circuit Board. I have Scanned/Itched the Logo of GoatIT over it. I designed it in Rhino-6 (.3DM file); exported from there as ".DXF" file and processed it in RD Works by importing it and then did the Laser utting of the ".RLD" file.

The design of LCD case was according to the LCD that I was using but it was not working later. So, I was given another LCD. I then Soldered the I2C module to it. This LCD was different than the previous one. I soldered the I2C module to it. It didnt had the Backlit. So, I didnt used the LCD case and fitted it directly in the Circuit Board Casing.

I powered up the Circuit Board with 5V 1 Ampere DC Adaptor for testing it. I also attached the ON/OFF switch, Reset Button and provision for Adaptor in the Casing. All the connections were shielded with Heat Shrink, Cable Tie and put under flexible pipe. The internal connections of the wires was twisted and Glue was applied to keep them in place.
I even marked the connectors to easily identify the inner and outer sides. I marked on the PCB and one side of the connector so that the two points could be matched and error in connections could be avoided.

The Logo of GoatIT and the Scanned/Itched Goat on the Case were not visible properly. So, I applied the Blue colored Vinyl Paper on the back side. I used the design of press fit and cut he Vinyl so that slots could be properly matched.

    Final Project Sketch/Code:

    The Code was prepared in stages. I first of all tested the Sensors (Input Devices) and the Output devices with the default pins on ESP32 module suggested by the tutorials and references on the Internet sources like RandomNerdTutorials, hackaday, LastMinuteEngineers etc.

    The Addresses of the RFID Tags were noted and incorporated in the Code. The Load Cell was Caliberated and the Caliberation Factor was included in the Final Sketch. A Channel dedicated to the Final Project - GoatIT was formed and edited to receive the readings. Its API write key was included in the Sketch. The SSID Address and Password of the WiFi was included for connecting the ESP32 with the Server/Channel.
    The MFRC522, HX711 modules and the LCD was tested in isolation. Then the ThingsSpeak code and WiFi were tested seperately. Then, all these codes were combined to form the Code for Final Project. The Codes are given in the Downloads section.

    Glimpse from my Final Presentation

    Prof. Neil suggested me to show the byte from the Video where Weight is displayed to confirm that the Project works. He also suggested to work on making the Casing Weather proof. I made the casing from Acrylic for aesthetic appeal. But, the circuit could be placed in a PPE box for better protection. After the deployment of this Project to Vigyan Ashram, they assured me of doing it.

    I have shot the video showing the readings of weight on the LCD screen.
