RFID sensor tags for environmental monitoring have 10m read range

May 16, 2017 // By Julien Happich
Powercast (Pittsburgh, PA) has announced what are claimed to be the industry’s first RFID sensor tags that can include multiple sensors in a single tag while providing the industry’s longest read range of 10m.

Designed for industrial and manufacturing applications where it’s necessary to monitor data to ensure goods don’t fall outside of acceptable parameters, the ultra-high-frequency (UHF) RFID Sensor Tags enable environmental condition monitoring throughout the shipping journey, for example, of temperature-sensitive pharmaceuticals or perishable products packed with dry ice.

The PCT100 enables battery-free wireless sensing and can read data within seconds. The PCT200 adds a battery with the unique ability to recharge using any standard RFID reader’s field, making the tag reusable without plugging in or changing batteries.

With up to one month of battery life without recharging, the PCT200 provides long-lasting data-logging capabilities while outside the RF field. Users can easily set its data read times from one minute to one hour. The tags use Powercast’s patented RF-harvesting technology where the embedded Powerharvester receiver can generate power purely from a standard RFID reader, transforming the signal into energy to power the microcontroller and sensors for measuring environmental conditions.

Operating in the 860 MHz to 960 MHz frequency range, from -40 to +85ºC, the tags can be configured with one, two or three sensors in any combination of temperature, humidity and light. The PCT100 can also be configured with an on-board LED for showing an RFID reader’s field strength and to verify that it is reading properly.
