RFID Sensors

RFID, or Radio Frequency Identification, is a technology that uses radio waves for data transfer and tagging objects. A RFID system consists of RFID tags, RFID readers, and antennas to facilitate wireless communication.

An RFID sensor is essentially a small integrated circuit (IC), or RFID chip, attached to an antenna. This combo, known as an RFID tag, can be attached to an object that needs to be tracked or identified. RFID tags come in different forms including RFID stickers, passive RFID tags, active RFID tags, and UHF RFID tags.

Passive tags do not have their own power source. Instead, they get activated when they come within the range of the RFID reader. These RFID readers emit radio frequency waves, and when these waves hit the tag's antenna, it induces a current that powers the chip in the tag. The chip then sends back information to the reader via the antenna. Active RFID tags, on the other hand, have their own power source and can transmit data at all times.

RFID tags can also incorporate sensor technology, resulting in RFID sensor tags. These tags can carry sensors such as temperature sensors or other types of sensors that can monitor physical parameters such as pressure, humidity, light, etc. The data from these sensors can be read wirelessly and in real-time, making them a key technology in many applications including supply chain management, inventory tracking, and many more.
