The EVAL02-Hygro-Fenix-RM is a UHF RFID battery-free humidity and temperature sensor tag with transparent polycarbonate casing. The device features a HTS221 relative humidity and temperature sensor from ST Microelectronics with a 0% to 100% humidity range and a -30°C to +85°C temperature range. The humidity and temperature sensor tag provides an accuracy of ±3.5% in humidity and ±1°C in temperature.

The tag is compatible with EPC C1G2 RFID commercial readers. No custom hardware or custom commands are required.

The EVAL02-Hygro-Fenix-RM is ideal for asset and process tracking as it provides a unique identification number plus ambient humidity and temperature data of the associated sensor. It works for applications such as leather manufacturing control or plant growing in greenhouses.
