  • Abstract
    This paper presents a low-cost, fully passive UHF RFID light sensor. We demonstrate how our design makes use of off-the-shelf photoresistors and LC components to establish a power frequency dependence which is used for improved sensor precision. Preliminary results show we can successfully identify 4 light intensity states between 0 to 1000 lux.
