P2110-EVAL-01

P2110-EVAL-01 Lifetime Power Energy Harvesting Development Kit for Wireless Sensors Users Manual - featuring PIC MCU with eXtreme Low Power (XLP) Technology 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. Contents The contents of the kit are shown in the image and table below. The kit includes an RF transmitter, RF energy harvesting receiver boards and antennas, wireless sensor boards, a PIC MCU-based development board and radio, and a programming tool.
