Recently, 2-frame interdigital fringe-field (ID-FF)-based capacitive sensors have been widely employed for soil moisture measurement. The present challenge with this design is to achieve both ...

As a bonus, we also give you the ambient temperature from the internal temperature sensor on the microcontroller, it’s not high precision, maybe good to + or – 2 degrees Celsius.” ...

Abstract: In this paper, we present the design, fabrication and calibration of a passive UHF RFID tag based soil moisture and environment temperature sensor. The inter-digital double-sided capacitive ...
