1. A wireless communication module comprising:
- a magnetic sensor configured to detect magnetic field data;
a communication circuit;
a controller in communication with the magnetic sensor and the communication circuit, the controller configured to;
monitor the magnetic field data;
compare a change in the magnetic field data to a first predetermined threshold; and
output an activation signal to the communication circuit in response to a change in the magnetic field data exceeding the first threshold;
wherein the communication circuit is configured to enter an active state in response to receiving the activation signal, wherein the controller is further configured to output a sleep signal configured to cause the wireless communication module to enter a dormant state in response to the magnetic field data being less than a second predetermined threshold for a predetermined period of time while the wireless communication module is in the active state.

Abstract
A wireless communication module is disclosed. The wireless communication module comprises a magnetic sensor configured to detect magnetic field data and a communication circuit. A controller is in communication with the magnetic sensor and the communication circuit. The controller is configured to monitor the magnetic field data and compare the magnetic field data to a first predetermined threshold. In response the magnetic field data exceeding the first threshold, the controller is configured to output an activation signal to the communication circuit. The communication circuit is configured to enter an active state in response to receiving the activation signal.
