Wireless identification and sensing platform
Appearance
A WISP (Wireless Identification and Sensing Platform) is a sensing and computing device that is powered and read by off the shelf UHF RFID readers. WISPs have on board microcontrollers that can sample a variety of sensing devices, creating a wirelessly-networked, battery-less sensor device. WISPs have powered everything from analog light sensors to temperature sensors to strain gauges. The computing features of WISPs have also been used by RFID security researchers.
