The 12V ESP8266 4 channel WIFI relay module uses ESP-01 as the WIFI module, and with the mature and stable 8-bit MCU chip, the wireless control of the four-way relay in the local area network can be realized by using the mobile phone APP in a simple configuration process.
The configuration of the account number and password of the ESP-01 WIFI module can be completed on the mobile phone APP, and the configured account number and password have the function of power-off memory.
The module has two working modes: mode 1: the mobile phone is directly mounted on the WIFI module; Mode 2: The mobile phone and the WIFI module are mounted on the router at the same time (additional function: it can also be used as a USB relay when the ESP-01 is unplugged)
Transmission distance: (1) In open environment, the maximum stable transmission distance when the mobile phone is mounted on the WIFI module is 100m;(2) When the WIFI module and the mobile phone are mounted on the router at the same time, the transmission distance depends on the signal strength of the router.
Onboard 5V,10A/250V AC 10A/30V DC relay, can be continuously drawn in 100,000 times, with diode laxative protection, short response time
Onboard mode selection and real-time working status indicator; with 4 optocoupler isolation, strong anti-interference ability; reserved UART debugging interface and MCU program download interface
