Powercast Corp.’s Lifetime Power wireless sensor system for HVAC control and building automation powers wireless sensor nodes without batteries or wires, but instead with remote transmitters that broadcast radio frequency energy. This system has three parts: battery-less sensor nodes embedded with Powerharvester receivers so they may be powered wirelessly, the WSG-101 BAS gateway, and the TX91501 Powercaster transmitter. One gateway can scale up to 800 sensor points and 100 sensor nodes including the WSN-1001 temperature and humidity sensor; the WSN-1101 temperature, humidity, and light sensor; and the WSN-1102 CO₂ sensor. The gateway interfaces to wired BAS networks via industry-standard protocols.
