Hi,
I need to change my outside PIR which operates two 60w lamps. It is very erratic and seems to be on far more than it should be, with no cause. It was a cheapo so I'm not complaining.
But it has also proved impossible to adjust properly. If set to respond to ourselves going out the front door, then cars going past on the road also set it off. So do bats flying near it, no matter what the setting, .
I have the idea that this PIR responds to both movement and heat. I wonder if, for our situation, one that responded only to heat would be best. Is there such a model? And would it respond well enough to the heat from a human body?
If such a thing doesn't exist, how could I find out the activation range of a better sensor before I bought it? It would have to be positioned carefully to do the job.
Hope somebody can help.
