Hi,  
I am looking for using a pair of IR emitters/sensors that connect to ESP32 boards (or Raspberry Pi).  
I am thinking to use this 3mm IR emitter ([https://www.digikey.com/en/products/detail/SIR-34ST3F/511-1363-ND/638559?itemSeq=376834696](https://www.digikey.com/en/products/detail/SIR-34ST3F/511-1363-ND/638559?itemSeq=376834696)) or a 5mm one ([https://www.digikey.com/en/products/detail/SIR-56ST3FF/511-1364-ND/638561?itemSeq=376834793](https://www.digikey.com/en/products/detail/SIR-56ST3FF/511-1364-ND/638561?itemSeq=376834793)). I believe both emit 950 nm wavelength. Could you help me identify any IR receivers that I can pair with the emitters?

Thanks.

Greetings,

General-purpose photodiodes useful around ~950nm can be found [here](https://www.digikey.com/short/1p5pwmnt). Depending on what you’re trying to achieve, a purpose-built [IR receiver](https://www.digikey.com/short/h288zjmf) designed for IR remote control applications might be convenient.
