Detecting passive RFID tags, the PHOTON UHF RF field detector operates battery free by harvesting the energy from the RF field. When a tag is detected, an LED sparkles. The stronger the RF field in a specific point and orientation, the brighter the LED will illuminate. Built in a PCB format, it is available in different sizes. The detection range is up to 3 meters for UHF RFID readers. For more details, visit http://www.farsens.com/en/product/16/photon-led-radio-frequency-field-detector
