Passive Products

As part of our roadmap, we have finished the first big step in the development of a batteryless remote monitoring system: the RF IC. We have just finished implementing our products in the following prototypes (check the links for more information):

 

 

Please check this video for a demonstration of a complete system running: 

 

 


 

We strongly believe that this small set of prototypes is already very interesting for a lot of applications. From logistics (cold chain monitoring) to asset management solutions (remote asset monitoring system, preventive maintenance), to healthcare applications (patient temperature monitoring) and many others, using a variety of sensors (strain gages, ambient light, gas, etc.), there is an impressive set of solutions that can be developed. Check the APPLICATIONS tab for more information on this topic.

 

Our final goal is to provide full wireless monitoring systems and we are now ready to continue with the development of other components to build them. In order to do that, we will have to:

 

  • select the appropriate sensor for each application
  • select commercial antennas or design and manufacture a set of antennas for different applications
  • select and prepare commercial readers for their utilization with sensor data (minor software to include sensor data request along with the identification number)
  • prepare a program for data output and management for client utilization

We have already covered quite a big area with low power sensors of different types, such as temperature, pressure, humidity and ambient light sensors, accelerometers, strain gages and so on. We have also worked on tunning antennas and preparing commercial readers at a prototype development level.

 

Companies working in any of the above areas interested in the potential of these products are welcome to contact us at any time for further information or partnership programs.

 

TECHNOLOGY

 

 

UHF RFID Technology


FARSENS has developed its first product with passive UHF RFID technology. The IC is compatible with EPC C1G2 compliant commercial readers, thus reducing investment in hardware and providing a flexible solution for our clients.

 

Current solutions for passive RFID sensors communicate to very short distances (up to 30 - 40 cms). Our goal was to create a system that increases that communication range so that new applications could be developed. For that reason, our first products work in the UHF band (868MHz - 920MHz).

 

Batteryless sensors
 
While developing our products, we also noticed that using external commercial sensors along with our own proprietary sensors to provide sensing data would be very interesting. For that purpose, 3 power outputs have been integrated in the IC so that external commercial sensors such as temperature sensors, accelerometers, pressure sensors, humidity sensors, etc. can be driven from the IC.
 
Then there is the IC - sensor communication. In our first product, we implemented a SPI communication protocol for this purpose. In addition to that, we are planning to implement the I2C standard in our next products for increased flexibility.
 
The objective is to create a Plug&Play philosophy oriented IC. Once the IC is powered wirelessly via commercial RFID readers, it is ready to supply and communicate with an external low power device.
