describe

Description：

The SPSXF001PET is a battery−free wireless sensor for moisture level detection on non−metal surfaces. Smart Passive Sensors use the Magnus−S2® Sensor IC from RF Micron, a UHF RFID chip that is powered by RF energy harvesting from the UHF reader. The Magnus−S2 utilizes the patented self−tuning Chameleon engine that adapts the RF front−end to optimize performance in various environmental conditions. Changes in antenna detuning due to moisture contact are digitized by the sensor which can then be read by a standard EPC Gen 2 compliant reader. These sensor tags function in either the FCC defined UHF band or the ETSI UHF band. The small form factor and battery−free capabilities of Smart Passive Sensors allow them to be designed into applications where size and accessibility are at a premium.
