Abstract: Automatic Smart Plant Watering System is a smarter solution that works on Arduino Uno, which can automatically operate for plant watering at optimal moisture conditions of soil. It checks ...

Use a capacitive soil moisture sensor (it’s corrosion-resistant). If using a resistive type, power the sensor only during readings (use a transistor or MOSFET controlled by Arduino).

Calibrate your sensor for your specific soil type. Record sensor values for “dry” and “fully wet” conditions and adjust thresholds in code. Optionally, use the map() function to create a more accurate ...

Abstract: Data from the NASA Cyclone Global Navigation Satellite System (CYGNSS) mission have shown promise for the retrieval of soil moisture, and many soil moisture products using CYGNSS data have ...
