Powercast to Demonstrate RF-Powered, Battery-Free Wireless Sensor Module at Sensors Expo 2010

May 31st, 2010


Powercast will participate as an exhibitor at the 2010 Sensors Expo & Conference.  At the event Power will be demonstrating a battery-free wireless sensor module powered by RF energy and designed for ultra-low power consumption.  The sensor module provides temperature and humidity data to an access point along with the received signal strength (RSSI) and the ID number of the Powercaster™ transmitter from which it is receiving power.

Powercast has recently released the P1110 and P2110 Powerharvester™ Receivers which are capable of converting radio waves in the range of 850-950 MHz into DC power.  The demonstration sensor module uses the P2110 Powerharvester receiver to store the received energy into a capacitor, and then performs a voltage boost to supply the module components will a regulated voltage.  Both the P1110 and P2110 enable a microcontroller to determine the signal strength of the received power, as well as to recover low-rate data encoded in the power broadcasted from the power transmitter.

Harry Ostaffe, Director of Marketing and Business Development for Powercast, will also be delivering two presentations during the event.  During the pre-conference symposium on June 7, 2010 he will speak on “Design Techniques for RF Energy Harvesting Devices”, and during the main conference on June 8, 2010 he will also present “Power Out of Thin Air: Ambient RF Energy Harvesting for Wireless Sensors”.

Powercast’s exhibit and wireless sensor demonstration will be located at Booth 1022 in the exhibition hall.
