Farsens presented Shadow, passive RFID tag for measuring light intensity

Passive RFID tag with light sensor.

The new addition to Farsens‘ range of passive RFID sensor tags is Shadow, a passive RFID tag that leverages a built-in photoresistor, or Light Dependent Resistors (LDR), to measure the intensity of light hitting the tagged object.  

Passive RFID tag for measuring light intensity


Fully compliant with the EPC Gen 2 standard, the Shadow is used in industrial automation and other applications that require to take actions in case the light level change. When interrogated, this passive RFID tag with light sensor is capable of transmitting its 96-bit EPC code along with a number between 0 and 100 corresponding to measured light magnitudes from 0 lux to 300K lux. Working without the need for a battery, Shadow allows to save any cost due to the maintenance necessary to battery-powered tags. Like all the Farsens passive RFID sensor tags, also Shadow is available in non-protected PCB formats for custom encapsulation and embedding in non-metallic assets/materials, or with fully customized encasements to meet any requirement in terms of mounting options and durability for use in harsh environments. Diverse antenna models are available to offer different directivity and read range.
