Description
This IoT development kit combines an ESP8266 NodeMCU Wi-Fi board, a dual channel relay module and a DHT11 temperature and humidity sensor for building wireless monitoring and automation projects.
The ESP8266 connects to a Wi-Fi network and processes sensor readings. The DHT11 measures ambient temperature and relative humidity, while the dual channel relay module allows two compatible electrical loads to be switched independently through suitable control logic.
Use this kit to prototype smart room monitoring, temperature-based fan control, automatic lighting, greenhouse monitoring and IoT dashboard projects. Additional wiring, a suitable power supply and programming may be required.
