If this is placed in a bathroom where there's a laundry in an immediately adjacent room, will this be triggered by the sound of the laundry running?

Asked by: BriD
Ultrasonic sensors detect the presence of people by sending out ultrasonic sound waves into a space and measuring the speed at which they return. They look for frequency changes caused by a moving person. Sound in a nearby room will not affect it's operation.
