ABSTRACT:
The present invention10provides a system and method of monitoring and tracking a plurality of physical variables from a remote location. The invention10utilizes a plurality of radio frequency identification transponders20each coupled with a sensor for measuring physical data. The transponders20are powered by a radio frequency reader/interrogator60that provides radio frequency excitation to the transponders20and receives and demodulates back-scattered signals therefrom. The invention10is particularly advantageous in monitoring temperature in cattle herds as an aid to early diagnosis of bovine respiratory disease.
