LinkNode Infrared Emitter Module
The Infrared Emitter is used to transmit infrared signals through an infrared LED, while there is an Infrared receiver to get the signals on the other side. An infrared LED is like any other LED, with its color centered around 940nm. We can not only use the emitter to transmit data or commands, but also to emulate remotes to control your home appliance using an Arduino.
The module is connected to the base shield J1:
Infrared TX --> LinkNode D1 G0
Place the IRremote library folder your ”arduinosketchfolder/libraries/ folder”.
Open “File->Examples->IRremoteESP8266->LinkNodeEsp-IRsend” and upload to your LinkNode D1.
This is just an infrared transmitter module, we also need an infrared receiver module.
You will need to prepare an additional Infrared receiver module and an Arduino board.
* Infrared receiver module please refer to the following link:
Open the Arduino IDE serial monitor ( BAUD 9600 , Please select the Arduino serial port, not the D1 serial port ) to see sensor data output. You can see the information below.
