I'm looking for a proven circuit design to receive binary data from an i-Lap/Kamtec compatible IR transponder.
I am trying to build a DIY receiver using an ESP32 (ADC pins) but have had no success with photodiode (PT333B) or TSOP38238 or VS838 receivers.
Could someone please point me toward a working schematic or advise if this requires a specific signal conditioning circuit (amplification/filtering) to work with the ESP32? Thanks!
