ESP8266 ESP-01S ESP01 S 5V WIFI RELAY MODULE

ESP8266 5V 1 Channel Relay Module suitable 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.

How to use:

1. 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 WIFI module mode of operation The
2. 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, USB to TTL module RX, TX, GND pin, then the module on the TX, RX, GND pin, IN +, IN – 5V power supply.

Introduction

1.  ESP8266 WIFI module, AP mode can be connected at the same time 5 client
2. 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.

Transmission distance:

1. Open environment, the mobile phone mounted on the WIFI module when the maximum transmission distance of 400m.
2. 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;

Control Commands :

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. ESP8266 wifi module; in AP mode it can connect with 5 Clients at the same time
11. Operating Way: cellphone carried on wifi module; cellphone and wifi module carried on the same router, and use APP to control relay
12. Transmission Distance : 400m (max)
13. Relay : 5V,10A/250V AC 10A/30V DC
14. Baud Rate: 9600.
15. Diode effusion protection;
16. Short response time
