Abstract
Disclosed are garage door sensor systems and devices that include one or more transmitter sources configured to transmit an electromagnetic (EM) waveform and one or more receiver circuits configured to receive the electromagnetic waveform from the transmitter source. The receiver circuit is configured to determine an active duration of the received electromagnetic waveform in a predetermined detection time window. The receiver circuit is configured to send a blocked beam signal based on the determined active duration and the predetermined detection time window. The blocked beam signal indicates to the garage door motor assembly that an obstruction is in the signal path between the transmitter source and a receiver sensor of the receiver circuit.
