Overview
®
The 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 (radio waves). It is designed and configured for extremely low power operation,
and the firmware is pre-installed for out-of-the-box operation.
The wireless sensor boards are powered by the P2110 Powerharvester Receiver, which converts RF
energy into DC power. In this 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. The communications from the sensor
boards to the access point is 2.4GHz using 802.15.4-compliant radios.
No batteries are needed to power the wireless sensor board. RF energy is converted into DC and stored
in a capacitor. When sufficient charge is stored the regulated output of the P2110 provides power to
the wireless sensor board until the operation is completed by the node or until the power is turned off
at the low-voltage threshold on the capacitor. The included wireless sensors measure temperature,
humidity and light, and have an interface for an external sensor.
