Battery-free IoT sensors using programmable UHF RFID sensor circuitry.
Battery-free IoT sensors combine extremely energy-efficient sensor technology with standard-compliant RFID protocols. The energy for the acquisition of measured values is supplied entirely by commercially available RFID readers. The UHF RFID circuit (LUNA1) will be presented, which can be used with a wide range of sensors thanks to its free programmability and can thus be flexibly adapted to a wide range of measurement requirements. Furthermore, the application of the battery-free sensors in a high-bay warehouse for zone-based monitoring of environmental parameters will be demonstrated.
