My partner and I have just installed some at our new home. A porch light for the front, one for the side driveway and one for the back garden. We spent Sunday evening trying to ‘sneak up’ on them to see how far we could get before the PIR detector spotted us… much to the amusement of our new neighbours who must have been wondering what on earth we were doing…I’m surprised our evening adventures weren’t followed by a visit from the local constabulary…
Everyone is familiar with them but I wonder how many people know how they actually work and what is inside them? I don’t! So… to satisfy my inner geek I spent some time surfing the internet to find out, and came across this ‘PIR teardown and tutorial’ on youtube which was rather interesting….
Now… to work out how to wire it up to an automatic water pistol contraption to keep next doors cat off the bonnet of the car…..
