FAST AFFORDABLE COURIER SHIPPING TO SOUTH AFRICA New toy for makers who want to build their own smart home system Overview: The wireless switch supports inching /self-locking mode. You can add the device to the APP eWeLink to remote control connected home appliances or devices. In self-locking mode, you can remote turn on/off connected devices immediately. When in inching mode, you have two wiring ways to select, whether turn on 1s and then auto-off or turn off 1s and then auto-on. Remote control by APP EweLink for iOS and Android. Supported functions include remote on/off, timing schedules, device sharing, group management. The self-lock/inching mode wireless switch has two power supply specification: 5V. No matter which specification you select, they have the same functions. Feature: There are two working modes for the module: inching mode and self-locking mode. Press the self-lock/inching mode button to switch between these two modes. When your module is switched to self-locking mode, you can turn on/off the connected appliance instantly. There is two wiring way. When your module is switched to inching mode, you can press on/off toggle button to turn on or off connected device. There are two kinds of wiring way. The first wiring way is to connect COM and NO with an appliance. In this way, when you press the setting button or APP to turn on, the connected appliance will be turned on for 1s and then auto turned off. The second wiring way is to connect NC and COM with an appliance. In this way, when you press the setting button or APP to turn off, the connected appliance will be turned off for 1s and then auto turned on. LED Indicator: There are 3 LEDs, the led beside self-lock/inching mode button indicates the working mode(on: self-locking mode, off: inching mode). The one beside on/off setting button indicates wifi status(enter pairing status: long press the setting button until led fast blink). Another one below the relay indicates relay on or off status(on: turn on the connected device, off: turn off connected device). Add device to eWeLink: Long press the setting button until the LED beside on/off setting button fast blinking. 1.

Summarize: 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: Onboard ESP8266 WIFI module, AP mode 5 client can be connected at the same time; Module has two work modes: 1, cell phones, carry on the WiFi module;2, mobile phone and WiFI module 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 Onboard 5 v, 10 A / 250 v AC 10 A / 30 v DC relay, absorb 100000 times continuously Module with diode effusion protection, short response time Module baud rate: 9600,8,1,0,0. The board function description:   Size: 45*28mm IN +,IN-: 5 v power input 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, AT+CIPSERVER=1,8080, configure the TCP server, set the port; 5, AT+CIOBAUD=9600 set the baud rate to 9600. (working in relays to control the baud rate 9600) 6, AT+CIFSR to view the AP mode IP address, such as: the APIP, "192.168.4.1"; 7, Cell phone WIFI signal connection name starts with AI-THINKER or ESP8266; 8, In the "TCP connection" address and port into the APP, such as 192.168.4.1 and 8080; 9, Click on the grey box relays can be controlled. 10,  Document: Applications:   1.
