5V ESP8266 Dual Channel WiFi Relay Module IOT Smart Home Phone APP Remote Switch

Features: 1.Onboard ESP01 WiFi module and high performance microprocessor STM8S103. 2. The module has 2 working modes: Mode 1: The phone is directly installed on the WiFi module. Mode 2: Equipped with a mobile phone and WiFi module on the router Additional features: It can also be used as a USB relay when the ESP01 is pulled out. 3. Transmission distance: In an open environment, when the mobile phone is installed on the WiFi module, the maximum stable transmission distance is 100M. When the WiFi module and the mobile phone are simultaneously carried on the router, the transmission distance depends on the signal strength of the router. 4.Use Smartcongig technology to complete the account and password configuration on the APP ESP01 WiFi module on the mobile phone, and configure the username and password memory functions. 5.
