I have successfully built a prototype that relies on IR emitters/photodiodes as a proximity sensor. But, it's build on a breadboard, and I just used these IR LEDs from Amazon to make it work:
Now I'm looking to assemble this project onto a circuit board, but I'm not sure which of the vast range of available optoelectronics available on Digikey or Mouser would give me approximately the same function as the LEDs I bought on Amazon.
Can anyone help guide me to a couple SMD package IR emitters/sensors that would function approximately like the Amazon LEDs?
