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 ...

The soil moisture sensor measures the moisture level in the soil. If the soil is dry, the Arduino triggers the relay to turn on the water pump. Once sufficient moisture is detected, the pump ...

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).

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 ...
