Temperature RFID sensors

The T-tags are devices based on UHF RFID technology able to sense, and wireless transmit, the temperature of the objects where they are attached, as well as of the surrounding environment. The sensors are suited to be placed over any material, including metals, and even onto the human body. They can be used in both passive (no battery required) and battery-assited (BAP) mode and can be customized, on request, in size and shape.

Some possible applications:

- Structural Health Monitoring...

Ed Yeates' Clip on iWalker

This video clip of iWalker was featured on Channel 5 KSL TV, Salt Lake City, Utah on March 4, 2008 by Ed Yeates.

This video features iWalker, a multi-sensor rollator-mounted wayfinding system for the elderly. The sensor suite consists of an encoder, a digital compass, and an RFID reader-antenna unit. The RFID antenna is attached to a PVC pipe in front of the walker, about 5 cms from the floor. It reads passive RFID tags in smart mats. A smart mat is a carpet with a grid of RFID tags...

RFID Tag Sensor Using Smart Attendance System

RFID tags:

Now, three different kinds of RFID tags are commercially available.

1) Passive tags

2) Active tags

3) Semi-passive tags

These passive tags do not have any power supply. They used to get their power from the incoming radio waves from the Readers.

While active tags have a power source for their internal circuitries. And for sending the response to the reader also, it uses its own power supply.

In the case of semi-passive tags, they have a power supply for internal circuitries,...

Readers for UHF RFID Wireless Sensors (Part 6 of 7) Tutorial

Learn more at http://www.phaseivengr.com - the inventors of battery-free wireless RFID sensing. Readers that support UHF RFID sensors are explained in this video. These readers include Intermec (Hand Held and Desktop), Feig OBID, ThingMagic, and custom readers. All of these readers (other than the custom reader) are off the shelf and use firmware developed by the reader manufacturer to read RFID sensor tags. The tags can be battery-free passive RFID sensors, Battery-Assisted Passive (BAP)...

Passive Wireless RFID Temperature Sensor Demonstration & Tutorial. Ideal for Food Safety.

RFID Sensors have the amazing ability to wirelessly transmit temperature data from a sensor that has no battery. The sensor uses the RF energy from the RFID reader to power the electronics and transmit the reading. No battery makes these sensors ideal in many applications, such as food safety. This video demonstrates the reading of a tag with multiple hand held readers. It also shows the performance of the tag at low freezing temperatures and against metal. The video highlights several of...

Arduino RFID switching

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves. Active tags have a local power source such as a battery and may operate at hundreds of meters from the RFID reader.

Using that system we have experimented lighting rate device which has ability to measure light intensity. The uniqueness...
