Ultra low power motion detection module. Utilizes the same pulsed Doppler radar technology as the BumbleBee, combined with an FPGA-based computing platform to achieve ultra low power operation. Pre-programmed with Samraksh's proprietary Displacement Detection algorithm, eliminating the need for additional mote hardware. Ships with its own enclosure for out-of-the-box installation. Key features:

• Based on Pulsed Doppler Radar sensing technology
• Tunable detection range up to 10m
• Single-board solution with on-board 20 MHz FPGA
• 40mW total power consumption, including 0.1mW FPGA consumption
• Robust motion detection via our proprietary Displacement Detection algorithm that rejects most common sources of false alarms
• Two-wire interrupt-style GPIO output for integration with external devices
• SPI bus connection option for integration with external networking or microcontroller modules
• Ships with enclosure for out of the box installation
• No programming needed. No need for attached mote

Due to its low power, cost and size profile, the GuardBee is suitable for a number of indoor and outdoor applications. Sample applications include people sensing, occupancy sensing, tripwire and area counting, residential and commercial security and energy profiling in indoor spaces, among others.
