This project developed an IoT-based microclimate control and monitoring system for oyster mushroom cultivation. The system regulates carbon dioxide (CO2) and humidity using an ESP32 microcontroller, which gathers data from a DHT22 humidity sensor and an MG811 CO2 sensor. It maintains CO2 levels below 800 ppm and humidity between 80 percent to 90 percent, ideal for mushroom growth. Based on sensor data, the ESP32 activates an intake fan and water pump to raise humidity or an exhaust fan to reduce CO2. Real-time data is monitored through a liquid crystal display (LCD) and wirelessly via the Blynk app for remote access.
