Farsens unveils battery-free RFID moisture sensor tag

The new HYDRO battery-free sensor tag is able to monitor the humidity level of a soil or any other material

Farsens unveils battery-free RFID moisture sensor tag

Farsens has introduced the HYDRO is a new battery-free RFID tag featuring a humidity sensor. The sensors are compatible with commercial EPC C1G2 compliant readers. Multiple HYDRO tags can be used in a short area and the reader will receive specific ID numbers with the associated humidity level data.

The HYDRO has a 96 bits EPC number, a 32 bit TID and a password protected Kill command. Built in a PCB format, it is available in different sizes. The read range is up to 1.5 meters and the operating temperatures are from -30°C to +85°C (-22°F to +185°F).

HYDRO tags can be embedded in different materials and read wirelessly from the outside for an effective moisture level monitoring. These tags allow for applications such as irrigation automation (activating irrigation just in the areas that require such activity) or detection of liquids in areas/items that should be completely dry.

Farsens, based in San Sebastián, Spain, designs and manufactures full passive RFID sensor solutions. Its proprietary UHF RFID IC allows Farsens to develop long range solutions for asset tracking – via the unique ID – and monitoring – via the attached sensor – without the need of any battery on the tag.
