Quick and dirty 38kHz IR sniffer
I threw this together because I wanted a braindead simple way to sniff IR data. This is pretty much just the receiver dump demos in IRremoteESP8266 except I output to OLED as well as serial port.
I'm currently using this to sniff my air conditioning unit's remote commands so I can control it through Home-Assistant. Also, who knows maybe I'll need something like this in the future for some other dumb thing I make.
- 1x ESP8266
- 1x VS1838B IR sensor
- 1x SSD1306 mini OLED
- 1x 470Ω resistor
- 1x 100Ω resistor
- 4x M2.5x10mm brass standoff
- 4x M2.5x6mm screw
- 2x Male header
