12V 2 Channel IoT Relay Module – Smart Iot Home Automation Relay

This 12V 2 Channel IoT Relay Module uses an ESP-01 Wi-Fi module and mature 8-bit MCU. The relay can be controlled by mobile app from anywhere in the world with the help of Internet. It is easy to setup. It has 2 different Relays which means you can control two different devices using this module. For functioning of this module, it should be connected to the internet via Wi-Fi. The module connects over wifi to the Iot server, and the mobile app will connect to the same IoT server, and the user will be able to toggle the relay On/Off using the mobile app.

The 12V 2 Channel IoT Relay Module should be configured prior to use. For one time configuration of this module, the user needs server credentials, wifi credentials and IP address of server. The Server IP address and the server credentials for the user will be given to the customer at the time of purchase via email. 

The 12V 2 Channel IoT Relay Module has different LEDs to determine the state of the module. A RED LED will light up when input power is supplied. When a operating signal is received an audible click can be heard as the relay triggers and LED for that relay would light up, connecting the output pins. Once it is programmed and powered it will look after itself, making it ideal for use in IoT based projects.

Function and Features:

• On board high quality MCU and ESP-01 WIFI module.
• 12V 2 Channel IoT Relay Module works as IoT relay and can be controlled from anywhere in the world with internet connectivity. 
• Additional function: work as normal Serial Relay module when ESP-01 module is removed
• The board contains 12V,10A/250V AC 10A/30V DC relay, which can continuously absorb 100,000 times, with the protection of diode current and short response time. 
• Reserved UART debug interface and MCU download port for program.
• Compact Board size ：58mm x 40mm 
• Input Voltage: 12V DC to IN+ and IN-
• UART serial port PIN: 5V, GND, TX, RX. 
• Reserved MCU download port: CLK, DATA, RST, GND. 
• 2 Pin short jumpers should generally be connected between RX-RX1 and TX-TX1
• Reset Switch: Pressing Switch S1 for 3 seconds will reset the 12V 2 Channel IoT Relay Module to factory settings and remove WiFi and server configurations
• Status and Mode LEDs
  • LED IN1/IN2（Red): Relay working LED, LED turns ON when relative relay is ON.
  • LED D7（Red)：It indicates MCU Power ON or NOT.
  • LED D5（Blue)：Indicates Hotspot created for initial configuration and sending credentials to module.
  • LED D6（Green)：It indicates the status of the module with details below.
    • Green LED is OFF: The module is not connected to wifi and server. 
    • Green LED is ON: It represents module is connected to Wi-Fi and is trying to connect to Server. 
    • Green LED blinks at 0.5 seconds : It represents Wi-Fi and Server is connected and module is ready to use.
• Max 3 user can be connected or access the module with no message rate limitation.

Note– You can Increase the user limit with nominal charges by contacting us.

Applications

This 12V 2 Channel IoT Relay Module can be used to literally turn ON/OFF any thing, located anywhere in the world (subject to WiFi internet connection), from your mobile phone. You can set this up without a single line of coding, just by following our easy to use guide. Apart from this, the module is connected to our low latency servers, which will ensure lowest reaction time, for better user experience.
