Wireless sensor system
A new wireless sensor by Powercast has been designed for monitoring in HVAC and building automation with a wide range of compatibility.
The Lifetime Power wireless sensor system from Powercast Corp. is designed for wireless environmental monitoring in HVAC control and building automation. Remote radio frequency (RF) transmitters broadcast RF energy that perpetually powers wireless sensor nodes without batteries or wires. The wireless sensor system is composed of three parts: a family of batteryless sensor nodes embedded with Powercast's Powerharvester receivers so they may be powered wirelessly, a WSG-101 BAS Gateway, and Powercast's TX91501 Powercaster transmitter. The WSG-101 BAS Gateway can scale up to 100 sensor nodes and 800 sensor points for large-scale deployment. The gateway interfaces to wired BAS networks via industry-standard protocols, including BACnet, Modbus, Metasys, and LonWorks. The sensors and gateway communicate wirelessly at 2.4GHz using 802.15.4 radios, which users can set to channels that will not interfere with, nor be interfered by, Wi-Fi networks.
