Reducing the influence of low temperature objects on PIR sensors? Answered
Hello, can anybody please help me with this? I was wondering if there was some sort of filter/material that I could place in front of a pir module, that would filter out any low temperature objects and only allow high amounts of infrared radiation to pass through and trigger the sensor (body heat). I plan to mount the sensor on a rotating turret, and when it spins I don't want the sensors to be triggered by the moving background (walls, bookshelves, etc.) thanks.
