Connected greenhouse.
An ESP32 connects temperature, soil moisture, irrigation, ventilation and light through a local web interface.
01 / The challenge
The question behind the system.
Bring environmental measurements and physical controls together in a small, locally accessible device.
A compact greenhouse controller combines sensing and relay-driven actuators on an ESP32. Its own Wi-Fi network and embedded HTTP server provide local monitoring and control without requiring a cloud service.
02 / The approach
From architecture to implementation.
- 01
Read digital temperature and analog soil-moisture inputs on the ESP32.
- 02
Switch the pump, fan and lighting through relay outputs.
- 03
Serve monitoring and control endpoints from an embedded web server on the local Wi-Fi network.
03 / Outcomes
What the work shows.
- The project documents the controller, power chain, sensor connections and local monitoring interface.
04 / Scope & next steps
Where the work stands.
- Soil thresholds depend on probe calibration. MQTT and Home Assistant integration are proposed extensions, not current capabilities.
