Wireless occupancy sensors and methods for using the same

Abstract

Wireless occupancy sensors and methods for using the same are provided. In some embodiments, an occupancy sensor includes: a magnetometer that detects changes in a magnetic field when a vehicle moves over the magnetometer; an optical sensor that detects one or more objects in a field of view of the optical sensor; a transmitter for transmitting sensor data to a gateway device, and a processor that controls the magnetometer, the optical sensor, and the transmitter. In some embodiments, the processor is configured to: detect, using the magnetometer, that a change in the magnetic field is greater than a particular threshold value; in response to the magnetometer detecting that the change in the magnetic field is greater than the particular threshold value, activating the optical sensor; receive, using the optical sensor, the sensor data associated with the one or more objects in the field of view of the optical sensor; and transmit, using the transmitter, the sensor data to the gateway device.
