UMich Moo
 A Batteryless Programmable RFID-Scale Sensor Device

 
Overview
The UMich Moo is a passive Computational RFID that harvests RFID reader energy from the UHF band, communicates with an RFID reader, and processes data from its onboard temperature sensor and accelerometer. Its function can be extended with its general-purpose I/Os, serial buses, and 12-bit ADC/DAC ports. The Moo provides a RFID-scale, fully programmable, batteryless sensing platform. The programs execute on an MSP430 microcontroller. The Moo 1.0 derives from the open source Intel DL WISP 4.1. Why is it called the Moo? It's the beefiest embedded platform in its class with the most code space and RAM for the least energy. The device also resembles a longhorn steer.

Video Tutorial

We presented an all-day, hands-on tutorial on how to develop programs for the Moo during the RFIDSec'11 workshop. You can't eat the tutorial lunch, but you can watch the video. We apologize for the lousy audio in the second video, but we'd be happy to answer any specific questions.
