The sensor wakes up every 15 seconds to measure this field. If the measurement has changed to a stable level, a message is transmitted through the Router Box to the Zone Controller. Even if no change is detected, the sensor will transmit the data to the Zone Controller every two minutes, to ensure the controller that it is still operating properly. Power to the sensor is supplied from 4 D-cells that provide a minimum battery life of 6 years. Wireless communication is achieved via X-Bee network technology. The complete wireless network between the sensor and the Zone Controller is made up of a Wireless Magnetic Sensor placed in each bay, a wireless router near to the monitored bays and a Coordinator which is connected to a Zone Controller.
