IR proximity sensor: how to keep the output signal high ...

May 05, 2021· Hi all, I am working on a project for my study, but have a small issue now. I made a simple proximity sensor, by using an IR LED and an IR Receiver (photo-diode). These circuits are relatively easy: turn on a LED if an obstacle is in front of the IR Receiver. However, what I want to add next is the following: - If an obstacle (a hand) is in front of the IR Receiver for 1000 ms or more (and ...
