SENSOR TAG DESCRIPTIONS
SPS1M001 – Quality Control Water Intrusion Sensor
Tag
The quality control water intrusion sensor tag is
specifically designed for the passive sensing of moisture in
finished goods as a form of leak detection. The sensors can
be placed in specific areas of the object and greatly
simplifies the quality control test for leaks. This Battery Free
Wireless Sensor can reduce the number of missed defects
and significantly improve the quality manufacturing lines.
SPS1M002 − Moisture Level Detection Sensor Tag
The moisture level detection sensor tag is specifically
designed for the passive sensing of moisture on various
surfaces and finished goods such as plastics, wood, and
plaster. The tag digitizes sensed moisture detection/level
information which can be read by a standard UHF RFID Gen
2 compliant reader. This Battery Free Wireless Sensor can
greatly enhance the reliability of the end product and offer
many benefits for deployment in industrial settings.
SPS1M003 – High Sensitivity Moisture Level Detection
Sensor Tag
The high sensitivity moisture level detection sensor tag is
specifically designed for the passive sensing of moisture that
does not touch the tag. This high sensitivity allows the tag
to detect moisture through layers of material making it ideal
for applications where the tag cannot be placed directly in
the area of interest. The tag digitizes sensed moisture
detection/level information which can be read by a standard
UHF RFID Gen 2 compliant reader. This Battery Free
Wireless Sensor can offer many benefits for deployment in
a variety of settings.
SPS2T001 − Temperature Sensor Tag
The temperature sensor tag is specifically designed for the
passive sensing of temperature experienced by the tag. The
tag digitizes the sensed temperature which can be read by a
standard UHF RFID Gen 2 compliant reader. This Battery
Free Wireless Sensor can offer many benefits for
deployment in industrial as well as agricultural settings.
