Resumen:
This article aims to propose a RFID system to detect the humidity of the soil in flowerpots and help farmers to judge whether the plants should be watered or not. By tuning the tag to dry soil state, it achieves higher dynamic range and sensitivity (20 dB) compared to a commercial RFID tag performance. This approach saves the addition of a sensor element to the RFID tag to operate as a wireless sensor.
