I was thinking of putting a PIR sensor in ceiling of a new small 1.5m x 1.1m W/C to switch on the light and fan.
Are these sensors susceptible to accidentally coming on because of a radiator heating up the area or because someone outside the obscured window, walks past? Are the sensors quite sensitive?
