Description

The ESP32 Relay Board is an electronic control board designed for switching electrical devices in automated systems. It integrates an ESP32 microcontroller with relay components to support programmable control functions. Depending on the model, the board may provide Wi-Fi or Bluetooth connectivity for wireless communication. It can be programmed to operate compatible electrical loads based on sensor inputs, commands, or predefined conditions. The board is suitable for smart home projects, equipment monitoring, and Internet of Things applications. Its installation requires appropriate power supply connections, compatible wiring, and compliance with the relay's electrical ratings. Buyers should verify the number of relays, operating voltage, contact ratings, communication features, and supported programming interfaces before purchasing.
