Description

Overview:
 
LC 5V ESP8266 2-channel WIFI relay module equip with to ESP-01 WIFI module and 8 bit high performance MCU, Only need simple configurations and then you can control the relay with cellphone APP under LAN area.

Characteristics:
 
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
8, Size: 59*40mm
5V ESP8266 Dual WiFi Relay Module Internet Of Things Smart Home Mobile APP Remote Switch
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 configurate 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
