Farsens unveils Battery-Free RFID Relative Humidity and Temperature Sensor Tag

Hygro-Fenix-H221 - Battery-Free RFID Relative Humidity and Temperature Sensor TagA full passive relative humidity tag with a temperature sensor from -40C to +120C degrees to monitor environmental conditions of assets

The Hygro-Fenix-H221 from Farsens S.L. is a battery free RFID sensor tag capable of transmitting a unique identifier and the associated relative humidity and temperature measurement data to a commercial EPC C1G2 reader without the need of a battery on the sensor tag. The device features an HTS-221 humidity sensor from ST Microelectronics with a measurement range from 20% to 80% rH with an accuracy of ±4.5 rH. It also offers temperature with an accuracy of ±1C degrees in the range from 0C to +60C degrees.

The tag comes in a variety of antenna designs and sizes to adapt the performance to the required application in the 860-960 MHz band. The reading distance for the battery-free thermistor tag is around 1.5 meters (5 feet) and it can be embedded in a wide variety of materials such as plastics or concrete. It can also be encapsulated in an IP67 or IP68 casing for usage in harsh environments. Evaluation kits are available.

The HygroFenix can be used without batteries at all, allowing for a wide range of opportunities monitoring relative humidity and temperature in applications where the accessibility is restricted, or where the use of batteries is not recommended. Since batteries are not needed, the sensor tags will never have to worry about autonomy.

The fact that HygroFenix tags need neither wiring nor batteries makes them perfect for applications such as datacenter infrastructure management (room humidity and temperature to enhance asset life-cycle).

Farsens designs and manufactures full passive RFID sensor solutions. Their 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.
