Abstract
An ultrasonic transmitter of an ultrasonic occupancy sensing device has adjustable ultrasonic signal output amplitude to prevent overload of an ultrasonic sensor associated with the ultrasonic occupancy sensing device. A circuit for controlling the operating voltage to a power driver of the ultrasonic transmitter allows field adjustment of the output thereof so that an optimal level (amplitude) for the transmitted ultrasonic signal may be found in an area of actual use (e.g., field adjustable).
