Abstract

Disclosed are garage door sensor systems and devices that include one or more transmitter sources configured to transmit an electromagnetic (EM) waveform and a plurality of receiver circuits configured to receive the electromagnetic waveform from a plurality of corresponding transmitter sources. Each of the plurality of receiver circuits and transmitter sources are configured to share a wired connection to a garage door motor assembly. According to some implementations the wired connection is configured to be coupled a low voltage power source of the garage door motor assembly. The receiver circuit is configured to send a blocked beam signal that 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.
