Description

The ESP8266 WiFi Relay Module integrates a high-performance ESP8266 WiFi module with a microcontroller, enabling wireless control of relays through a mobile app within a local area network (LAN). This dual-channel relay module is specifically designed for controlling higher voltages, supporting up to 250V AC and 30V DC, making it ideal for various applications such as operating remote lights, managing appliances, and triggering systems based on signals from the ESP8266 module. Equipped with LED indicators that reflect the module's operational status, it features a red power activation LED that illuminates when a signal is received on the IN pin. Users will hear an audible click when the relay activates, connecting the output pins. The relay is controlled by the ESP8266 module, which requires initial configuration via UART commands. Once programmed and powered, the module operates independently, making it an excellent choice for Internet of Things (IoT) projects.
