Abstract

Oyster mushroom cultivation is highly influenced by environmental conditions, particularly temperature and humidity. The challenge is even greater in dry climate regions such as the Middle East, where high temperatures and low humidity prevail, thus requiring an automated system to maintain stable incubator conditions. This study designs and implements a temperature and humidity control system based on an ESP32 microcontroller with a DHT22 sensor as the main detector. Temperature control is carried out using a PID algorithm with exhaust fan and PTC heater actuators, while humidity control applies a two-position (hysteresis) logic with a pump and mist nozzle actuator. Temperature and humidity data are displayed in real time through the Blynk application, which also allows setpoint adjustments via smartphone. The test results show that the system can maintain incubator conditions according to the defined setpoints, with stable temperature response and effective humidity control without excessive pump switching. Therefore, this system improves the efficiency and reliability of oyster mushroom cultivation in dry climates with less favorable environmental conditions.
