APPARATUS AND METHOD FOR PROVIDING PRODUCT INFORMATION

摘要

A sensor system comprises a tag. The tag comprises at least one sensor, an analog to digital converter, a passive radio-frequency chip, and a first antenna. The sensor is adapted to provide an output analogous to a change in an environment of the sensor. The sensor produces an analog output and includes output terminals. The analog to digital converter is adapted to convert an analog output of the sensor to a digital value. The analog to digital converter includes input and output terminals. The input terminals of the analog to digital converter are disposed in electrical communication with the output terminals of the sensor. The passive radio-frequency chip comprises a memory element, input terminals and output terminals. The input terminals are disposed in electrical communication with the output terminals of the analog to digital converter. The first antenna is disposed in electrical communication with the output terminals of the chip.
