What are RFID Sensors?
RFID sensor tags monitor environmental changes and events and transmit the information to an RFID reader through a wireless connection. In instances where measurements must be taken remotely and automatically, these telemetry products are perfect. The RFID temperature sensor tags could detect changes in motion, humidity, temperature, pressure, and more, depending on the RFID temperature sensor tags.
Do these tags require an external power source?
No, the sensor RFID tags, which collect energy from radio frequency waves emitted from the reader and antenna, are battery-free.
