Situation: a tunnel between terraced houses which needs an automatic light to come on when approaching from either end.

Most PIRs I've used give a click when operating, which implies some sort of relay. Therefore, it ought to be possible to simply wire two PIR detectors in parallel. However, some lights with integrated PIR do not work with low energy loads, which suggests that the circuitry is not completely isolated from the load (as it would be with a relay).

So, are there PIR detectors out there that can be wired in tandem?

You might want to try This one

I have lots of them in the garden, they last for years, I admit never wired them in parallel, but for the price I would try it.
