relayESP8266 5V Wifi Relay ModuleProduct parameters:Product size: 45*28mmWorking voltage: DC5VCommunication method: WIFI (ESP8266 module)Serial communication parameters: 9600,8,1,0,0Transmission distance: The maximum transmission distance is 400m (in an open environment, when the mobile phone is equipped with a WIFI module)Load: 10A/250VAC 10A/30VDC, the relay pulls 100,000 timesWay of working:1. The mobile phone is mounted on the WiFi module;2. The mobile phone and WiFI module are mounted on the same router, and the relay is controlled through the mobile APP; the transmission distance in this mode depends on the signal of the router.1. The onboard ESP8266 WIFI module has three working modes: STA (client), AP (hotspot), and STA+AP (client + hotspot). Choose the working mode of the WIFI module according to the working mode of the module. .2. Before using the module, you need to use the serial port debugging software and the USB to TTL module to send serial commands to configure the WIFI module. The RX, TX, and GND pins of the USB to TTL module are connected to the TX, RX, and GND pins on the module (ESP8266 The default baud rate of the module is generally 115200 or 9600. When it is 115200, you need to send AT+CIOBAUD=9600 to set the baud rate to 9600, otherwise the relay cannot be controlled correctly), IN+, IN- connect to 5V power supply.3. After the configuration is complete (note that the 5V power supply cannot be unplugged, because some parameters of the WIFI module cannot be saved after the power is off), install the "TCP connection" APP on the Android phone, open it and click "Connect", enter the IP address and port number , Click "connect", then click "switch" in the interface, long press the gray square in the interface to add a serial port command, enter the name and content of the command (when the command content is A00101A2, turn on the relay; when the comm
