NFC Passive Monitoring Sensor
Based on the TN21 NFC energy harvesting IC, Chivotech developed a long-term sensing platform, which utilizes NFC smartphones or NFC charging trays to charge internal battries/supercapacitors. It can be configured (sensing interval, sensing precision, alarm setting, storage policy) in the field with NFC phones and dedicated readers. After activation, the sensor can work for months relying on the internal energy storage. NFC phones and readers can retrieve the sensing data stored inside the sensor. It can be recycled and reused after charging again.
