Moisture Detection Sensor for Healthcare

The RFM2121 battery-free moisture detection sensor is applied to the outside of garments and can detect the presence of liquid. The typical use is in healthcare and Smart Diaper™ settings. The sensor can be read wirelessly through bedding and clothing. Healthcare workers can determine if patients need attention.


The RFM2121 is available in FCC and EU/ETSI frequency ranges. The RFM2121 Smart Sensor™ requires a RAIN/UHF compliant reader. These sensors can be purchased separately or as part of a kit.
