My Conservatory is finally finished (Which I am sure you will be glad

I am thinking of fitting a PIR sensor off of my house alarm, just to
give me that extra bit of protection.

Is a PIR a good idea in a construction like this.

As the temperature will fluctuate, could this trigger the PIR.

But more imporantly, because its almost entirely glass, can a PIR "see
through" the glass, to anything moving outside?


I Have had a dual-tec pir sensor in my conservatory for three years
now and never had a false alarm.
