Hi,
I wonder if someone might be able to point me in the right direction, bit of a specialist one this I think
I'm looking to build a PIR movement detector project, but with a slight difference. I need the PIR to be able to distinguish between large and small 'heat' masses, in a similar way that a 'Pet safe' sensor does (on a typical home alarm for example).
The difference being that I'd like to be able to change/tweak this "setting" as required and detect either a large, or small heat source.
Does anyone know how this might be accomplished? Would this be a case of adding some kind of processing that would be able to test the signal and respond approprietly (i.e. ignore a small heat source), OR would there be some other way to approach this?
Any shoves in the right direction would be very welcome, thank you.
