Description

The ESP8266 WiFi Relay Module integrates an ESP8266 WiFi module with a microcontroller, enabling wireless control of high-voltage devices within a local area network (LAN) through a mobile app. This versatile relay module is perfect for projects requiring the control of larger voltages, allowing users to activate devices with up to 250V AC and 30V DC safely and efficiently. Equipped with a state indicator LED, the module provides real-time feedback on its operational status. A red power activation LED illuminates when a signal is received on the IN pin, while the audible click signifies that the relay has triggered, establishing a connection between the output pins. The relay operation is managed via the onboard ESP8266, which requires configuration through UART commands for initial setup. Once configured and powered, the module autonomously manages its operations, making it a suitable choice for Internet of Things (IoT) applications.
