Powercast brings remote, wireless power capability to micro-power devices such as wireless sensors, data loggers, active RFID and RTLS tags, and more. RF energy harvesting technology from Powercast breaks new ground in remote, wireless power by increasing the efficiency of converting RF energy (radio waves) into DC power and enabling that efficiency over a wide operating range. Powercast’s embedded wireless power technology allows battery replacement to be reduced or eliminated by trickle charging rechargeable batteries or using super-capacitors and thin-film energy cells.
The Powercast Wireless Sensor System is made up of the Lifetime Power Wireless Temperature and Humidity Sensor (WSN-1001), the WSG-101 Building Automation System (BAS) Gateway, and the TX91501 Powercaster Transmitter. The parts of the Powercast Wireless Sensor System work together to transmit accurate temperature and humidity measurements in real-time through a BAS network with a wide range of physical interfaces and industry standard protocols including BACnet, Metasys, Modbus, and LonWorks.
The Powercast Lifetime Power® Energy Harvesting Development Kit for Battery Charging is a complete demonstration and development platform for wireless battery-charging over distance powered by RF energy (radio waves). This Powercast development kit features a THINERGY® Micro-Energy Cell with credit card-size form factor and extremely low leakage. The Lifetime Power Energy Harvesting Kit for Battery Charging includes a Texas Instruments eZ430-RF2500 wireless development tool for demonstration purposes. The kit's batteries are charged by the P2110 Powerharvester Receiver®, which converts RF energy, stores it into an intermediate capacitor and provides a pulsed, regulated voltage output that provides charged current to the attached storage. In this Powercast Lifetime Power kit, the TX91501 transmitter is the source of RF energy at 915MHz, but other sources from 850-950 MHz can also be used for power. A regulated load voltage is provided to power an application device.
The Powercast 2110 Powerharvester™ 915 MHz Receiver is an RF energy harvesting device that converts RF to DC. The Powercast P2110 receiver is housed in a compact SMD package and provides RF energy harvesting and power management for battery-free, micro-power devices. The P2110 can also pulse-charge batteries as is done in the P2110-EVAL-02 kit. The Powercast P2110 converts RF energy to DC and stores it in a capacitor. When a charge threshold on the capacitor is achieved, the P2110 Powerharvester Receiver boosts the voltage to the set output voltage level and enables the voltage output. When the charge on the capacitor declines to the low voltage threshold the voltage output is turned off. This Powercast Powerharvester Receiver is ideal for use in battery-free wireless sensors, wireless triggers, and low power electronics.
Powercast P1110 915 MHz RF Powerharvester™ Receiver is an RF energy harvesting device that converts RF to DC. The Powercast P1110 Powerharvester Receiver is housed in a compact SMD package and provides RF energy harvesting and power management for battery and capacitor recharging. The P1110 converts RF energy to DC and provides the energy to the attached storage element. When an adjustable voltage threshold on the storage element is achieved, the P1110 automatically disables charging. This Powercast Powerharvester Receiver is ideal for use with wireless sensors, wireless triggers, and low power electronics.
The Powercast Lifetime Power® Energy Harvesting Development Kit for Wireless Sensors is a complete demonstration and development platform for creating battery-free wireless sensor applications powered by RF energy. This Powercast kit features a Microchip Technology PIC® MCU with eXtreme Low Power (XLP) Technology and includes an RF transmitter, RF energy harvesting receiver boards and antennas, wireless sensor boards, and more. The wireless sensor boards of the Powercast Lifetime Power Energy Harvesting Development Kit are powered by the P2110 Powerharvester Receiver, which converts RF energy into DC power. No batteries are needed to power the wireless sensor board. RF energy is converted into DC and stored in a capacitor.
