The 5V dual WiFi relay module uses ESP-01 as the WiFi module and is compatible with 8 bit MCU chip. Only a simple configuration process can realize the wireless control of the 2 way relay by using the mobile phone APP .
Function:
1. Onboard ESP-01 WiFi modules and high performance microprocessor STM8S103 .
2 The module has 2 operating modes of work:
Mode 1: mobile phone is directly mounted on WiFi module.
Mode 2: mobile phones and WiFi modules are equipped on routers simultaneously
Additional function: it can also be used as USB relay when ESP-01 is pulled out.
3.Transmission distance:
In an open environment, the maximum stable transmission distance is 100M when the mobile phone is mounted on the WiFi module.
4. When the WiFi module and mobile phone are carried on the router at the same time, the transmission distance depends on the signal strength of the router.
5. Onboard 5V, 10A//250V AC 10A//30V DC relay, which can be continuously pulled for 100 thousand times, has diode discharge protection, short response time.
6 .The use of Smart congig technology in the mobile phone on the APP ESP-01 WiFi module to complete the account and password configuration, configured username and password memory function.
7.Board mode selection and real time working status indicator.
8. Reserved UART debug interface and STM8 SWIM program download interface.
Description

Details

Description:

1, On-board N76E003/STM8S003 and ESP-01 WIFI module
2, Having two modes:
(1) Mode 1: Cell phones carry on the wifi module directly
(2) Mode 2: Cell phone and wifi module carry on the same router
Additional function: As an USB relay module when unplug the ESP-01
3, Transmission distance:
(1) In the open environment, the maximum transmission distance is 100m when the cell phone carry on the wifi module directly ;
(2) when the wifi module and cell phone carrying on the same router, the transmission distance depend on the router’s signal intensity;
4, Use Smartconfig technology of ESP8266 to configurate the password for the
ESP-01 module with APP
5, On-board 5V, 10 A / 250 v AC 10 A / 30 v DC relay, absorb 100000 times continuously, Module with diode effusion protection, short response time
6, On-board model selection and working position indicator LED
7, On-board preserved UART debug interface and MCU program interface


Interface and sources:
 
IN+, IN-: 5V power input
TX, RX: UART communication
SWIM, NRST: MCU program interface
S1: Mode selection key, default is mode 1
S2: Restore key
LED D2 and D4(red): Relay indicator
LED D7(red): Mode 1 indicator
LED D5(blue):  Mode 2 indicator
LED D6(green): Working state indicator, the description of D6 as below:
(1)It’s means internal self-configuration or lost connection with the router when D6 off
(2)It’s means the ESP-01 are waiting for the APP configuration the password for it when D6 fast blink every 0.5S
(3)It’s means the whole configuration is done and waiting for establishing TCP connection with APP when D6 slow blink every 2S
(4) It’s means the TCP connection between ESP-01 and APP is OK when D6 on all the time.
Relay control command(must be hex format):
Open the first relay: A0 01 01 A2
Close the first Relay: A0 01 00 A1
Open the second relay: A0 02 01 A3
Close the second Relay: A0 02 00 A2

Package included:

1 x 5V ESP8266 WiFi 2CH Relay Module with ESP-01 WIFI module
