Abstract
The invention is a microminiature wireless environmental sensor that has integrated both sensor and transmitter functions into one function. The basic operating principle for the device is that variable components of an RF circuit can be interfaced to the outside world environmental signals resulting in proportional changes in the transmission characteristics or transmission of data/bits from the RF transmitter circuit. This utilization of environmentally sensitive variable elements within a wireless transceiver circuit permits the fusion of both sensor and communications function into an integrated single function.
