Description
This is WiFi relay module based on the ESP8266 serial module. And it controls the relay working status through the APP. Perfect kit for controlling all your household appliances with your phone wherever you are.
Method of application:
1. ESP8266 WIFI module has three operating modes: STA, AP and STA + AP.
You can choose the operating mode according to the working mode of the module.
2. Before you use the module, you need to use the serial debugging software and USB to TTL module to send serial port command to configure the WIFI module. And please connect the RX/TX/GND pins of USB to TTL module to the module's RX/TX/GND pins.
(The default baud rate of the ESP8266 module is 115200 or 9600. When it's 115200, you need to send AT + CIOBAUD = 9600 and set the baud rate as 9600, otherwise the relay can not be properly controlled). And connect the IN +, IN- to the 5V power supply.
3. After the configuration is completed, please install the "EasyTCP_20" APP on the Android phone. Then click "Connection" and " Open". Please be noted that the 5V power supply cannot be off, or some parameters of the WIFI module will miss.
Then press the column in grey in the interface for entering the serial command, the command name and content(open the relay module when the content is A00101A2, while close the relay when it's A00100A1).
Please send the commend in the form of hexadecimal. And you can control the on/off of the relay module by clicking the related columns.
For more detailed info, we'll email to you once we receive your order. Please check your email box. Thanks.

7. ARCELI New ESP8266 5V 10A DC 7-30V Network Relay WiFi Module
Feature
Transmission Distance:400m (max)Onboard Module:ESP8266 wifi module;in AP mode it can connect with 5 Clients at the same tim
Relay:5V,10A/250V AC 10A/30V DC 5.Baud Rate:9600,8,1,0,06.Features:diode effusion protection;short response time
On-board 5V, 10A/250V AC 10A/30V DC relays, which can continuously pull 100,000 times, with diode escaping protection and short response time;
Description
1. Onboard ESP8266 WIFI module can connect 5 clients simultaneously in AP mode2. The module has two working modes:
(1) The mobile phone is directly mounted on the WIFI module;
(2) The mobile phone and WIFI module are installed on the router at the same time.
3. Transmission distance:
In the open environment, the maximum transmission distance when the mobile phone is mounted on the WIFI module is 400m;
When the WiFI module and the mobile phone are installed on the router at the same time, the transmission distance is strong according to the signal of the router.
Weaker

Hardware introduction and description
Board size: 45*28mm
Board function description:
IN+, IN-: 5V power input;
TX, RX, GND: serial debugging pins;
How to use:
1. The onboard ESP8266 WIFI module has three working modes: STA (client), AP (hot spot), STA+AP (client + hotspot), and correspondingly selects the working mode of the WIFI module according to the working mode of the module. .
2, the module needs to use the serial port debugging software and USB to TTL module to send AT commands to the WIFI module configuration on the computer, USB to TTL module RX, TX, GND pin connected to the module on the TX, RX, GND pin, IN+, IN- connects to 5V power supply.
3. The default baud rate of the WIFI module is generally 115200 or 9600. It can be modified by sending an AT command, for example: AT+CIOBAUD=115200. In general, 115200 is recommended, but 9600 should be used when using a mobile phone to control the relay. The on-board MCU (STC15F104W) has a baud rate of 9600 baud.
