Powercast’s Multi-Sensor RFID Tags Boast 10 Meter Read Range

The industry’s first RFID Sensor Tags which can include multiple sensors in a single tag, and provide the industry’s longest read range of 10 meters, or 32 feet.

“We call it high-function RFID because these new passive RFID Sensor Tags have more than 10 times the operational power of standard passive RFID tags enabling advanced features and unparalleled computing power,” said Dr. Charles Greene, Powercast COO/CTO.

RFID Journal LIVE! (PRWEB) May 09, 2017 — Powercast Corporation, the leader in wireless power-over-distance technology for 14 years, today announced the industry’s first RFID Sensor Tags which can include multiple sensors in a single tag, and provide the industry’s longest read range of 10 meters, or 32 feet. High accuracy temperature, humidity and light sensors are now available, with more sensor types planned for the future. Tags for sensing the RFID reader’s field are also available and use an on-board LED to show field strength.

Designed for industrial and manufacturing applications where it’s necessary to monitor data to ensure goods don’t fall outside of acceptable parameters, the ultrahigh 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.

Powercast offers two versions of its high-function RFID Sensor Tags:

  • 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.

Powercast’s Patented RF Harvesting Technology Enables Efficient, High-Function RFID:

The RFID Sensor Tags use Powercast’s patented RF-harvesting technology where the embedded Powerharvester® receiver can generate power purely from a standard RFID reader.

How it works:

An RFID reader generates an electromagnetic signal, which the Tag’s NXP UCODE RFID chip captures via its receiving antenna. Powercast’s efficient, RF-to-DC converter (50-75% conversion efficiency) then transforms the signal into energy to power the microcontroller and sensors for measuring environmental conditions. The microcontroller then forwards that data over I2C to NXP’s RFID chip for storage in user memory, which the reader can then read out of memory.
