SPSXT001PET Smart Passive Sensor for Temperature Sensing Description The SPSXT001PET is a battery free wireless sensor for temperature monitoring on nonmetal surfaces. Smart Passive Sensors www.onsemi.com use the MagnusS3 Sensor IC from RF Micron, a UHF RFID chip that is powered by RF energy harvesting from the UHF reader. The MagnusS3 utilizes the patented selftuning Chameleon engine that adapts the RF front end to optimize performance in various environmental conditions. These sensor tags function in either the FCC defined UHF band or the ETSI UHF band. The small form factor and batteryfree capabilities of Smart Passive Sensors allow them to be designed into applications where size and accessibility are at a premium.
