TempTrackr wireless temperature measurement system kits read six independent passive, wireless temperature sensors.
Each sensor operates in a unique frequency band to prevent cross-talk with other sensors. This also provides them unique identification within system architecture.
The sensors are based on surface acoustic wave technology. They require no batteries or external power source, but are powered by electromagnetic bursts generated by a wireless receiver. It serves to power the sensors and listen to response signals generated by them. A change in frequency-of-response signal is indicative of change in a temperature being measured.
TempTrackr is highly scalable. It accommodates up to 12 wireless temperature sensors with appropriate setup and configuration. Additional details are yours free.
