I need some help please ! The house already has a number of PIRs wired in throughout the house, these all work fine but I want to make this a 'smarter' arrangement and access the PIR outputs via an arduino board - that I can subsequently link into a home automation alarm set up I have.
I am not an electronics expert but have done quite a bit of research including following this thread and setting up the same circuit
https://forum.allaboutcircuits.com/threads/home-alarm-pir-signal-question.120439/
but having done that my problem is I am no detecting the PIR triggered motion - ie when the NC circuit goes open. If I physically break that circuit I see the output go high but I am not seeing anything or the PIR triggered motion.
Is my problem linked to the properties listed here https://books.google.co.uk/books?id...epage&q=arduino nc circuit pir sensor&f=false
In that I get high for a break in circuit , I get low for a short, but I am not seeing the impact of the PIR triggered change ?
