摘要: The present invention 10 provides a system and method of monitoring tracking plurality physical variables from remote location. utilizes radio frequency identification transponders 20 each coupled with sensor for measuring data. are powered by reader/interrogator 60 that excitation to the receives demodulates back-scattered signals therefrom. is particularly advantageous in temperature cattle herds as an aid early diagnosis bovine respiratory disease.
