Radio Frequency Identification (RFID) Sensors
Radio Frequency Identification (RFID) sensors use electromagnetic fields to wirelessly identify and track objects equipped with RFID tags. These tags contain unique information and can be passive or active. Passive tags draw power from the RFID reader's signal, while active tags have their own power source. The RFID reader emits radio waves, prompting the tags to transmit data back. RFID sensors find applications in inventory management, access control, and logistics, providing a non-contact and efficient means of data collection. They operate on various frequencies, such as low-frequency (LF), high-frequency (HF), and ultra-high-frequency (UHF), offering versatile solutions for diverse industries.
