Abstract

Broiler chicken farming requires a stable environmental condition, particularly in terms of temperature and humidity, to support optimal growth and prevent thermal stress. To overcome the limitations of manual temperature regulation, an automatic temperature control system was designed based on the Proportional Integral Derivative (PID) algorithm using an Arduino Nano microcontroller. This system utilizes the DHT22 sensor to read temperature and humidity, while a keypad allows users to input the desired temperature set point. The PID output signal is used to regulate the power of a PTC heater through an AC Light Dimmer module using Pulse Width Modulation (PWM). Additionally, two fans serve as a ventilation system: an exhaust fan to expel hot air and a cooling fan to introduce fresh air. Testing demonstrated that the system could maintain the cage temperature close to the set point of 34°C with a relative sensor error of only 0.86%. Four rounds of PID tuning were conducted, resulting in optimal parameters of Kp = 21.8, Ki = 0.048, and Kd = 3800. These results show that the system offers more stable and efficient temperature control compared to conventional on-off methods. Furthermore, the system is designed to operate offline without an internet connection, making it suitable for implementation in remote farming areas.
