ESP8266 WiFi 5V 1 Channel Relay Module IOT Smart Home Remote Control Switch

ESP8266 WiFi 5V 1 Channel Relay Module IOT Smart Home Remote Control Switch is equipped with ESP8266 WiFi module and micro-controllers, through the mobile phone APP to the module to send serial instructions to achieve in the LAN within the relay for wireless control. This onboard 5V, 10A / 250V AC 10A / 30V DC relay, can be continuous pull 10 million times, with diarrhea flow protection and short response time.

Features :

• Onboard ESP8266 WIFI module, AP mode can be connected to 5 client at the same time.
• The module has two ways to work:
• (i) mobile phone directly mounted on the WIFI module;
• (ii) mobile phone and WIFI module also carried on the router.
• Operating Way: cellphone carried on wifi module; cellphone and wifi module carried on the same router, and use the APP to control relay
• Diode effusion protection;
• Short response time

Transmission distance:

• Open environment, the mobile phone mounted on the WIFI module when the maximum transmission distance of 400m.
• When the WiFI module and mobile phone at the same time carried on the router when the transmission distance according to the router’s signal weakly;

Board function description : 

• IN +, IN-: 5V power input;
• TX, RX, GND: Serial debug pin;

How to use :

• Onboard ESP8266 WIFI module has three operating modes: STA (client), AP (hot), STA + AP (client + hot), according to the work of the module to select the corresponding choice of WIFI module working mode. 
• The module needs to use the serial debugging software on the computer and USB to TTL module to send AT commands to configure the WIFI module. (make sure that no power outages occur 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.

Control Commands :

When cell phone equipped with WiFi module sends commands in the following order:

(The default baud rate 115200)

• AT+CWMODE=2, namely AP mode is selected.
• AT+RST, reset.
• AT+CIPMUX=1, open multiple connections.
• AT+CIPSERVER=1,8080, configure the TCP server, set the port.
• AT+CIOBAUD=9600 set the baud rate to 9600. (working in relays to control the baud rate 9600).
• AT+CIFSR to view the AP mode IP address, such as the APIP, “192.168.4.1”.
• Cell phone WIFI signal connection name starts with AI-THINKER or ESP8266.
• In the “TCP connection” address and port into the APP, such as 192.168.4.1 and 8080.
• Click on the grey box relays can be controlled.

Package Includes :

• 1 x ESP8266 WiFi 5V 1-Channel Relay Module
