Microchip and Powercast Release RF Energy Harvesting Kit for Battery-Free Wireless Sensors
Powercast, with the development support of Microchip, has released the Lifetime Power® Energy Harvesting Development Kit for Wireless Sensors. This kit provides wireless power for remote, battery-free wireless sensor networks (WSN).
The kit (part number P2110-EVAL-01) includes the following items:
1 - 3W Powercaster Transmitter - 915MHz (TX91501-3W-ID)
2 - P2110 Evaluation Board (P2110-EVB)
2 - Directional, patch antennas - 915MHz
2 - Omni-directional dipole antennas - 915MHz
2 - Wireless Sensor Boards (WSN-EVAL-01)
1 - Microchip XLP 16-bit Development Board
1 - Microchip 802.15.4, 2.4GHz radio
1 - PICkit programmer/debugger
The components in the kit enable wireless and battery-free operation of the sensor nodes at a distance of 40-45 feet (13-15 meters). Each sensor board can measure temperature, humidity, light, and an external sensor. This can be used for a number of applications including building automation, energy management and industrial monitoring. Power is provided by Powercast’s new 3W transmitter (TX91501-3W-ID), which also sends factory-set data. The P2110 Powerharvester receiver converts the RF energy from the receiving antenna and stores it into a capacitor, which is then boosted to operate the wireless sensor board. The Microchip XLP 16-bit Development Board with the 802.15.4 radio is the access point.
