Matter-Compliant, Wireless Smart-Home Sensor Tech Driven by OTA Charging
Powercast has developed untethered, Matter-compliant wireless smart-home automation sensors for integration into smart-home ecosystems that eliminate the need for wiring or battery maintenance. The Wireless Smart Home Automation Sensor solution is constantly powered by the company’s RF over-the-air (OTA) charging technology. This charging methodology can enable battery-free or rechargeable-based sensors and other low-power always-on devices to power themselves OTA from nearby RF transmitters. The Powerharvester PCC110 wireless RF receiver chip requires a small antenna, and one RF transmitter in a room can power sensors installed up to 25 feet away.
The RF transmitters offer a licensable reference design to integrate the electronics needed for products to use Ubiquity RF transmitters. The range for OTA RF charging depends on device power consumption, with ultra-low-power devices like IoT sensors able to operate up to 120 feet away. Devices using more power must be placed closer in relationship to their power demand. The technology complies with the Matter smart-home connectivity standard and Thread wireless communications, using the IEEE 802.15.4 mesh network. The Powerharvester PCC110 receiver chip (in a SC-70 package) operates across a wide RF power (-17 to +20 dBm) and frequency (10 MHz to 6 GHz) range to convert RF to DC with up to 75% efficiency.
