Battery free sensors are the next generation of RFID (Radio-frequency Identification) tags, energised by harvesting the emitting wave energy from the RF (Radio Frequency) field of an RFID reader. These RFID tags are capable of not only providing unique identification, but also energizing an attached sensor and measuring a physical or chemical property. RFID battery free sensors cover a wide their applications from on-farm to off-farm practices, research to commercial use. As an example, for a battery free soil moisture sensor, an RFID reader utilises the electromagnetic fields to automatically identify and track the RFID tag and measure the attached soil moisture sensor. These sensors can be deployed across farms for management of irrigation systems. This paper will review the application and viability of RFID battery free sensing technology and its application in digital agriculture for both research and commercial uses through case studies.
