AJMRTC ESP8266 WiFi relay module adopts the mature ESP-12F WiFi core module, turning ordinary electrical devices into WiFi-enabled smart switches. It accepts wide-range DC input from 7V to 30V, and its relay contacts can handle loads up to 10A under 220V AC, suitable for controlling lights, pumps, fans and other household or industrial low-power equipment. Optocoupler isolation effectively suppresses interference between the WiFi control part and high-voltage load circuit, greatly lowering the risk of static and surge damage. The module comes with power and relay status LED indicators for quick status checking. It supports remote trigger via WiFi, serial port debugging and common IoT protocols such as MQTT. You can customize the firmware for automatic timing control, linkage trigger and mobile remote control. Perfect for smart home transformation, greenhouse monitoring, equipment power control, student electronic projects and DIY IoT automation builds.
