Description:

A soil moisture sensor measures the water content in soil and can be easily integrated with an Arduino Uno to build projects like an automatic watering system or a smart garden monitor. Most sensors provide an analog output that can be read by the Arduino's analog input pins.

Specifications:

Resistive Soil Moisture Sensor (e.g., YL-69)
Principle: Measures the electrical resistance between two exposed probes; more water leads to less resistance and a higher analog value.
Capacitive Soil Moisture Sensor (e.g., Gravity: Analog Capacitive Soil Moisture Sensor- Corrosion Resistant)
Principle: Measures the change in capacitance based on the soil's dielectric permittivity; the sensor provides an analog voltage output corresponding to the moisture level.
