ESP32-based poultry egg incubation system integrates PID control, Firebase cloud monitoring, and automated actuator management for precision hatchery operations. DHT22 sensors feed temperature and humidity data to the ESP32 microcontroller, which drives heating elements, cooling fans, humidifiers, and servo motors through relay modules while maintaining closed-loop feedback control. Firebase cloud database enables remote monitoring via smartphone app, allowing farmers to track incubator conditions, receive notifications, and send control commands over WiFi. This architecture demonstrates industrial IoT principles applied to agricultural automation, combining embedded systems, cloud connectivity, and real-time control for optimized egg incubation. Fork this diagram on Diagrams.so to customize sensor types, add redundancy layers, or adapt the control logic for your own precision agriculture projects.
