Here is an interesting application of pressure sensors in a wireless environment. CAN2GO’s Variable Air Volume (VAV) building automation controller has an on-board pressure sensor and is capable of bidirectional communication with EnOcean and wired end-devices. EnOcean is rapidly becoming the defacto standard for wireless building automation.
The controller features an embedded EnOcean transceiver and EnOcean-to-BACnet gateway, allowing total wireless control of energy harvesting end-devices within an end-to-end BACnet system. Extending the reach of centralized building automation systems, the VAV controller is a fully-programmable device. The pressure sensor is used as a delta-P flow sensor. It has a measurement range of -500 to 500 Pa (-2 to +2 inch H2O) and an accuracy of 3% m.v. The CAN2GO controller can act either as a stand-alone product or be integrated into a larger BACnet system.
