Hi what is a TSOP sensor and why use it instead of IR transmitter-receiver?

The TSOP is a series of infrared receiver which is capable of receiving infrared radiation modulated at 36kHz only. This can be advantageous in many situations such that stay radiation hardly affect the receiver/sensor. I should also tell you that the TSOP is a receiver, not an emitter.

You can use any infrared emitter, and modulate the signal by providing an electric signal of 36kHz to the IRED or whatever you are using Ashaan.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
