My Conservatory is finally finished (Which I am sure you will be glad
to hear means no more questions)

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?

You can get PIR sensors specifically designed for harsh environments like
conservatories, have a look at www.tlc-direct.co.uk
