Energy Company Testing Passive RFID Sensor for Equipment

A global energy company is testing a newly released passive sensor tag that measures temperature levels—and, in one version, mechanical strain—then transmits that data to nearby readers via UHF RFID. The AS321X chip was developed by French technology company Asygn. A preliminary version was being tested as early as spring 2019, while the latest iteration is now ready for commercial-scale rollout.
