Bathroom lights/fan on PIR advice | AVForums

· I use a PIR to trigger the fan. The lightswitch is outside too, but that might be awkward as you need a standard backbox depth really. With regards to the fan, there are a number of trigger permutations - (1) on whilst sensing movement and set time after, (2) a humidistat which obviously only comes on when humidity builds up and (3) an air quality sensor.

· a PIR, so that whenever someone enters the bathroom - regardless if the lights are switched on or not - the fan switches on automatically, and uses the built in fan timer.
