LC 5V WiFi relay module carried a ESP8266 WiFi module and microcontroller. It will send the serial port instructions to the cell phone APP and Implementation within the local area network (LAN) for wireless control relay.
Function and characteristics: 1. Onboard ESP8266 WIFI module, AP mode 5 client can be connected at the same time; 2. Module has two work modes: Cell phones, carry on the WiFi module; Mobile phone and WiFI module 3. Carrying on the same router, by mobile phone APP to control relay
Transmission distance: 1. The open environment, the mobile phone when carrying on the WIFI module maximum transmission distance of 400 m 2. When the WiFI module and cell phone carrying on the router at the same time the signal transmission distance in accordance with the router On the weak 3. Onboard 5V, 10A / 250V AC 10A / 30V DC relay, absorb 100000 times continuously 4. Module with diode effusion protection, short response time 5. Module baud rate: 9600,8,1,0,0.
The board function description: 1. Size: 45*28mm 2. IN +, IN-: 5V power input 3. TX, RX and GND: a serial port debug pins
Introduction: Onboard the ESP8266 WIFI module has three work modes: STA (client), AP (hot), the STA + Ap( hot +client), according to the workings of a module to the corresponding choice of WIFI module working mode.Module need before use serial debugging software and USB to TTL module send serial command was carried out on the WIFI module configuration (don't power outages after configuration is complete, as some of the parameters of WIFI module cannot be saved when the power is cut off), mobile phone and WIFI module after establishing a network connection can use the phone APP control relay. When cell phone equipped with WiFi module sends commands in the following order: (The default baud rate 115200) 1. AT+CWMODE=2, namely AP mode is selected; 2. AT+RST, reset; 3. AT+CIPMUX=1, open multiple connections; 4. A
