Everybody talks about Bluetooth and Wi-Fi. But one heavily used technology is often forgotten: Infrared. Today we will remember this technology and bring it into the today's world of microcontrollers like ESP32 and ESP8266 and to technologies like MQTT and node-red. And as usual, we will dig a little into the basics.

Today

  • We will use infrared rays to detect objects
  • And find a way to make the detector immune against interference from daylight
  • We will use standard photodiodes as well as IR receivers to detect IR signals and see the difference
  • Then we will use IR instead of LoRa or Wi-Fi to transport information over the air
  • We will enable an Arduino UNO to receive, learn, and send IR codes
  • We will port the IR library to the ESP32 and implement MQTT
  • Finally, we will build a device which can control our home appliances like TVs or Lights
  • This device should be able to receive signals from an IR remote controller and transfer them via MQTT to Node-Red
