We present an approach for making an RFID capable of sensing multiple measurands. In this approach, sensor's information is carried in the modulation frequency. Analytical expressions describing the sensor's operation are reviewed and, for the first time, this kind of sensor capable of measuring two quantities, humidity and illumination, is experimentally demonstrated. Finally, we demonstrate a generic multi-sensing platform by using humidity and light sensors. Results show that humidity and… CONTINUE READING
