Powercast Releases Battery-less, Wireless-powered Sensor System for Building and Industrial Automation
Powercast has released a battery-less, wirelessly-powered sensor system for building and industrial automation - the Lifetime Power® Wireless Sensor System. The sensor units can be powered at a range of 60-80 feet (18-24 m) from Powercast’s 3W, 915MHz transmitter (TX91501). The initial sensor unit is for temperature and humidity and is to be followed by other types such as CO2, light, and motion.
Powercast Lifetime Power® Wireless Sensor System
The access point (WSG-101 BAS gateway) supports up to 100 sensors and 800 sensor points for large-scale and high-density deployment of sensors. The sensors are battery-free and operate when sufficient charge is stored to take sensor readings and send a data packet. Wireless communication from the sensor nodes to the access point is 2.4GHz using industry-standard 802.15.4 radios. The BAS gateway supports several physical interfaces and a range of BAS protocols to interface with nearly every major type of wired BAS network, including BACnet, Modbus, Metasys N2, and LonWorks.
The system was developed based on the same core technology as the Powercast P2110 Powerharvester receiver and the P2110-EVAL-01 Energy Harvesting Development Kit, both of which are available for other sensor OEMs to embed Powercast’s technology into their own products.
