Abstract
The idea is to design a cost efficient incubator box which is primarily used to hatch eggs by controlling it's temperature and humidity with the help of PID algorithm. By setting the set point values of temperature and humidity on Nextion Human to Machine Interface(HMI) touchscreen one can set the desired value for the parameters to control. PID algorithm is developed which is nothing but a software code which will check for each instant that the process variable value being fed back to the controller is greater than or less than the desired set point value and perform controlling action given to the actuator so as to achieve desired temperature and humidity. Actuator circuit used is an electromechanical relay which will perform switching operation as soon as the process variable goes above and below set point . Glass heater tube is used as an heating element which will be connected to the relay whereas a motor pump and DC operating fan is used to generate humidity and to distribute it inside incubator box .
