Unpowered RFID tag reports temperature

July 08, 2013 // By Graham Prophet
The Fenix2 is a wireless, battery-less sensor that tracks temperature condition of assets and processes.

The Fenix2 from Farsens S.L., Spain, is a battery-free RFID sensor tag. These tags are compatible with commercial EPC C1G2 readers and communicate a unique ID and the associated temperature data without the need of battery supply on the sensor tags. The Fenix2 tags can communicate to around 1.5m and, as they transmit through materials such as plastics or concrete, they can be embedded in inaccessible locations. These battery free sensor tags will operate in a range of -30°C to +85°C (-22°F to +185°F). The Fenix2 is available in different antenna design and sizes.

The fact that the sensor is fully passive makes the battery free temperature sensor ideal for restricted areas and those where the use of batteries is not recommended.

The typical applications for the Fenix2 are temperature sensitive assets and processes. Each tag has a unique ID and a temperature sensor that is uniquely associated to that ID. It makes the Fenix2 a solution for applications such as cold chain monitoring or fire prevention for high value assets such as switchgears). Evaluation kits are available.
