ceiling PIR noise

[chrisdias]

Hi -

I recently installed this motion detector in a bath so that i could turn walkway lights on at night...

It works great, and i can turn off the red LED, but it still produces a subtle "click" whenever it detects motion. This noise is starting to have a negative impact on the WAF...

Anyone know of ceiling PIRs that don't make noise?

thx,
chris

That click is the reed relay...I don't know of any that use anything else.

You can always replace the relay with something along the lines of an opto-isolator (generally $0.50 each from a electrical surplus warehouse).
