Project Summary

In manual control shed, 24/7 monitoring of the shed is impossible, and chickens require a suitable temperature and humidity level for survival. Poultry needs standard temperature and humidity, set with 20?-25? and 60%-80%, respectively. Programmable Logic Controller (PLC) is used as a controller, which controls the poultry farm's feed, temperature and humidity through sensor. “Pronem-mini temperature and humidity sensor” is used to control the temperature and humidity inside the poultry farm. The conveyor mechanism is used for feeding purpose. 

                 The model consists of boundary of acrylic sheets. The sensor always senses the temperature and humidity and when one or both rise or fall with respect to the designed value, the PLC will turn fan, heater or humidity fire on and off automatically. Similarly, a time duration is set in ladder logic programming of PLC to provide feed at the intervals of 8 hours. The feed is poured into hopper and from hopper it is dropped into conveyor belt, which further moved to a container from where chickens will be fed. Water is supplied to a separate container by pressure pump.

Project Objectives

 Following are the objectives of our project:

1. Modification of old manual method of control shed.
2. Automatically control temperature, humidity, feed and water.
3. Decrease the labor cost and human errors.
4. Decrease the wastage of feed.

Enhance the lives of chickens.

Project Implementation Method

This project will comprise of Programmable logic Controller (PLC), Pronem-mini temperature and humidity sensor, Programming cable, heater, fans, humidity fire, pressure pump, containers, hopper and conveyor belt.

                Ladder logic programming is done first in which all the parameters like standard temperature, humidity, timing of feed and water is described and is burnt in PLC. We set the temperature range. If temperature falls below that range, the sensor senses and provides signal to the PLC which then turns heater and fan on. The heater and fan is adjusted in such a way that heater provides heat and fan throws its heat, in order to maintain temperature fast. Similarly, when temperature rises above range fan will turn on.

                A range of humidity also set in the programming, when humidity drops with respect to that range the sensor sends commands to PLC and then PLC will on humidity fire. Similarly, when humidity increases above range then sensor senses and PLC will turn on the fan. A hopper is designed on the top of conveyor belt. When time to give feed comes the feed will drop from hopper to conveyor belt, belt will move, and drop to the container, until it get fills. Similarly, water will also provide through pressure pump to a separate container.

Benefits of the Project

The benefits of project are:

1. Labor cost reduces.
2. Less human errors.
3. Health of chicken increases.
4. Handling of control shed will be easy.

Technical Details of Final Deliverable

Technically, the complexity level of this project is high. In software based designing, the first thing is to implement is ladder logic. For this, we downloaded GX developer version 8.91 for ladder logic programming of Mitsubishi PLC.

In hardware, the proper set up of feed part was difficult. The synchronization of the Conveyor belt with PLC and choosing the appropriate motor to carry feed without wasting was important. For this we made boundary around conveyor belt and made level of hopper as low as possible to avoid wasting when it fells on conveyor belt.

            Providing water without damaging other equipment’s was technical. For this, we attach relay with pressure pump. When relay got signal it will connect with pump, otherwise it will disconnect.

           The last problem we faced is the amount of feed to provide at once. It depends on the size of container. For this, we run the projects for different duration of time, note the time at which container fills, and made that value final.
