Publication number: 20240077629Abstract: The adjustable voltage regulator under control of a microcontroller applies controlled amplitude voltage in the range of 5 to 9 VDC to the sensor transmitter to adjust the output amplitude of the transmitter. The adjustable amplitude transmitter allows an occupancy sensor to have its total output energy adjusted to reduce environmental noise-induced false triggering and to conform to the area to be covered. Lowering the total ultrasonic energy in the monitored space lowers the sensitivity of the receiver to inappropriate activations. Lowering the input power to the transmitter also lowers the total internal system noise and provides an improved signal to noise ratio in the receiver.Type: ApplicationFiled: September 18, 2023Publication date: March 7, 2024Applicant: The Watt Stopper, Inc.Inventors: Louia Weidman, Aizhong Chen, Chenghao Fan
