With 1-channel power indicator, each relay has status indicator lights up and relay
The relay module can be extended up to 8 outputs, Note: The relay module should be actived high
You can configure the module through the network parameters, such as the module IP address, default gateway, etc.
Holding relay status before power down (configurable)
Through internet control, remote cloud by local password protection, safe and reliable
Supports 5V or 9-24V input voltage
1.6mm thick PCB by the military grade FR-4 sheet material, PCB size 70mm X 50mm, set aside the mounting holes
1 x Delay relay TCP / UDP module controller
Function features :
1.on board high quality MCU and ESP-01WIFI module
2.two working mode :
Mode 1:cellphone carry on wifi module directly
Mode 2: cellphone and wifi module carry on router together
Additional function :work as USB module when disconnect ESP-01 module
3. Transmission distance:
(1) the open environment, the mobile phone when carrying on the WIFI module maximum transmission distance of 100 m;
(2), when the WiFI module and cell phone carrying on the router at the same time the signal transmission distance depends on router signal
4. Use the Smartconfig technology to complete the configuration of the account and password of the esp-01 WIFI module on the mobile APP. The configured account and password will be memorized after power off
5. The board contains 5V,10A/250V AC 10A/30V DC relay, which can continuously absorb 100,000 times, with the protection of diode current and short response time.
6. With mode option and working statue LED indicator
7. With 4 isolator and strong anti interference ability
8. Reserved UART debug interface and MCU download port for program
Hardware introduction :
Board size ：60*63mm
1，interface on board ：
IN+、IN-：5V voltage input ；
5V、GND、TX、RX：UART serial port PIN ；
SWIM、PIN8、NRST：reserved MCU download port 。
Button S1：change mode ，default mode is mode 1
LED D1/D2/D3/D4（red ）：relay working LED，LED on when relay is on
LED D7（red ）：indicator for mode 1
LED D5（blue）：indicator for mode 2
LED D6（green ）：work statue indicator ，exact details as below ：
(1)When extinguished, it is being configured or disconnected from the router.
(2)0.5s fast blinking represents cellphone app is configuring WIFI account and password for ESP-01 module
(3) 2S slow blinking to configure finished ,and wait for connection with cellphone by TCP
(4)LED always on represents TCP connections with mobile phone successfully
Connection for reserved two cap jumper :
Generally ,insert them to bottom ,that is RX to RX1,TX to TX1 .Insert them to upper ,when use it as USB module

Tips: all of the following are used to control the first 2 relay in the mobile phone APP. The third and fourth way are the same, except that the relay control instructions are different.
2，get ready for the following software and tools ：
(1)5V/1A adaptor and connect to IN+ and IN-；
(2)Install APP “EspTouch_Demo” android version to configure wifi account and password for ESP-01 module on the first time of mode 2
This ESP-01/01S Relay based on AI-Thinker ESP-01/01S WIFI module. It is designed for smart home, Internet of thing and others DIY project. With this smart relay, you will easy to DIY your smart switch to control any device by your phone anywhere. We support the APP and LUA source code.
In the version, we use the GPIO0 of ESP-01 OR ESP-01S to control the Relay by Low level.
Working voltage: DC5V-12V
Working current: ≥250mA
Communication: ESP-01 or ESP-01S WIFI module
Transmission distance: the maximum transmission distance of 400m (open environment, mobile phone equipped with WIFI module)
Load: 10A/250VAC 10A/30VDC, the relay pulls 100,000 times
GPIO0 of ESP-01/01S Control the Relay (Low level active)
Product size: 37 * 25mm
Just plug the ESP-01/01S to the 2*4 pin header after download the code to ESP-01/01S. Show as below:
Connect a DC 5V-12V power to the GND and VCC.
Open your phone WLAN then connect the WiFi ESP8266-XXXX, Power word:12345678
Open the ESP8266 Controller.app ( Installed it in your android phone before)
Set IP Address: 192.168.1.1 than you can control your device via the wifi relay module
