RFID (Radio Frequency Identification) sensor systems are a wireless and batteryless communication technology that enables data measurements (temperature, pressure, etc.) and identification using radio waves. These systems offer virtually unlimited sensor lifespans and are used in numerous industrial sectors.

 

Such a system typically consists of three main components: an RFID sensor, a reader, and a data processing computer. This technology allows for contactless data measurement over distances ranging from several centimeters to several meters.

 

Our team has extensive expertise and experience in designing RFID sensor systems, thanks to our patented wireless technology for harsh environments. Prestigious clients have benefited from our expertise.

 

Here are some examples of our projects and products in this field:

Remote Pressure Measurement

 

RFID pressure sensors installed in the tires measure tire pressure and temperature. This information is transmitted to a stationary reader (Drive By Reader) as vehicles pass by the reader antennas, and then accessed through the online customer portal.

Our team contributed to design of this system for Michelin Trucks North America. For more information about this project and how it works, click here.

 

Remote temperature measurement

 

A system specifically designed by PNEUGRAPH for monitoring the axle temperatures of the New Delhi Metro Rail Corporation's metro system. Thanks to our patented RFID technology, this battery-free and wireless system can operate in the harsh and high electromagnetic interference environment of metro stations.

It consists of temperature sensors equipped with PNEUGRAPH RFID technology and stationary readers positioned near the tracks. Upon passing of a metro train the batteryless sensors are activated and transmit data (temperature + ID) to the readers.
