Based upon a proven and standardized IEEE 802.15.4 technology, the evolution from wired to wireless monitoring is occurring to reduce costs, including installation and setup time, improve uptime, save energy, and improve workplace safety. For example, battery powered wireless sensors can be used to indicate the open or closed status of small pocket doors used in an airplane hangar. Cables and wires would quickly be twisted and broken by the motion of the large hangar door.
In many instances, wireless is the best solution for applications where cabling to connect traditional switches or sensors are not economically or technically feasible, such as mounting on moving doors and equipment. It is much simpler to use a wireless sensor that transmits the door’s open or shut status to a monitoring system. This can include hanger doors at airports or in a facility with numerous access panels, windows and vents. During the summer, a vent left open can let expensive air conditioning escape, while in the winter, heat escapes. Using wireless to monitor the status of these access points is becoming common. A sensor on each vent or window can be transmitted to a monitoring station or transmitted over the web to a SmartPhone with a custom created app. For security, the wireless connectivity features a 16-bit address and 128-bit AES security key.
