Hi Forum!
I am seeking some advise about how to build an IR sensor using discrete components instead of the ready out of the box TSOP circuits out there.
I am using a TSOP 7000 with an Arduino today and it works okay but not great.
it is a TSOP 7000 because I an capturing and decoding IR signals from a Bang & Olufsen remote and they use a 455 KHz carrier frequency instead of the more common 38 KHz.
The trouble is the low sensitivity of the TSOP7000 which makes me think I may need to find a new solution. I more or less have to aim the remote diectly at the sensor for it to pick up the signal. It works from across the room but I have to aim it carefully. Compare this to original B&O equipment which seem to be able to pick up the signals no matter in which direction I point the remote. My conclusion is that they are not using TSOP 7000 in their products, or they are able to get them at a much higher quality.
I have tried a few different TSOP7000 sensors and they are more or less the same I would say.
So I am tninking I may need to build a sensor from scratch, using an IR diode and discrete components, in order to get better performance. But I have absolutely no idea how to do that to be honest.
Any advise from the forum would be very appreciated.
