Abstract
A system comprising a magnetic sensor circuit for detecting a magnetic field, a magnet in close proximity to the magnetic sensor circuit, a wireless transceiver, and a controller. The controller coupled to the magnetic sensor circuit and to the wireless transceiver, and having a sleep operating mode and an awake operating mode, storing executable instructions which, when executed, cause the controller to receive a first signal from the magnetic sensor circuit indicating a lack of presence of the magnetic field. In response to the first signal, send a second signal, via the wireless transceiver, to a remote server indicating the reusable system is awake, and switch from the sleep operating mode of the controller to the awake operating mode, wherein the awake operating mode of the controller listens for a third signal from the magnetic sensor circuit. In response to the third signal, the controller performs a function.
