Some active RFID tags have input and output ports on their circuit boards, enabling users to connect sensors and have sensor data transmitted to readers. There are also a wide variety of active RFID sensors already on the market that can detect temperature, humidity, vibration, acceleration and radiation.

Some passive high-frequency (HF) and ultrahigh-frequency (UHF) tags also have input/output ports that allow you to connect sensors. Most passive RFID sensors on the market are temperature loggers.
