Summary: Abstract--This paper presents a wireless, battery-free,
platform for sensing and computation that is powered and read
by a standards compliant Ultra-High Frequency (UHF) Radio
Frequency Identification (RFID) reader. The WISP (Wireless
Identification and Sensing Platform) includes a fully-
programmable 16 bit microcontroller with analog-to-digital
converter. The microcontroller firmware implements portions of
the Electronic Product Code (EPC) Class 1 Generation 1
protocol. When queried, the platform communicates arbitrary
sensor data by emulating an EPC tag whose ID encodes the
desired sensor data; the required 16-bit CRC is computed
dynamically by the microcontroller. The RFID reader reports
the received tag ID to application software which can interpret
the information contained in the tag ID. The programmability of
the WISP along with its implementation as a PCB allows for
flexible integration of arbitrary low-power sensors. Furthermore,
sensors are also exclusively powered from the RFID reader
resulting in a completely battery free device. Sensors integrated
into the WISP platform so far include light, temperature, and
rectified voltage, and are shown experimentally to have an
