I have an Infra-Red detector pointing down my garden an last night it triggered many times and lit up the garden ... There were no Birds , Dogs , Cats , Foxes or anything else that I could see that could cause the triggering.
I eventually got fed up and checked my garden for any moving tree or shrub branches that might be the culprit ... It was a very calm evening with no movement of foliage ... I eventually got out my Solarforce torch to examine the detector which is about eight or nine feet above ground level ... I found the culprit.
A spider was building a web in front of the sensor and as he (or she) was walking backwards and forwards across the sensor , the 500 Watt light was being switched on ... I relocated the spider (into next doors garden) and I hope that she (it has to be a she) does not cause me any more aggro.
I always thought that the PIR could only be triggered by a warm-blooded animal !
Still the problem is now solved.
