Temperature Control System in Egg Incubator Based on PID with Graphical User Interface

Typically, egg incubators available for purchase utilize on-off control to regulate incandescent lamps, which might result in temperature changes. The objective of this research is to develop a temperature control system for the incubation of chicken or duck eggs using PID control with graphical user interface and monitor the humidity level. The DHT11 sensor detects the current temperature and humidity. The target temperature are 37 degrees celsius. The process of temperature regulation is achieved by implementing PID control to adjust the power supply of the incandescent lamp in order to maintain a stable desired temperature. The actual humidity will show in GUI then the user could set on / off the mist maker to disperse water, in conjunction with an exhaust fan. The microcontroller used is the Arduino Nano. The Python QML programming language is used to develop a graphical user interface (GUI) for real-time monitoring and control of temperature and humidity conditions. This interface allows for the adjustment of setpoint settings and PID control parameters. Simulation and validation have been conducted in the context of temperature control. The system has rise time of 47s, settling time of 411s and maximum overshoot of 2,64%. The system has the capability to regulate temperature (37 degrees Celsius) with slight fluctuations.
