This product measures soil moisture levels using capacitive sensing rather than resistance like other types of moisture sensors. It is made from corrosion-resistant material, giving it a long lifespan.
The product includes a built-in voltage regulator that provides an operating voltage range of 3.3 ~ 5.5 V. It is compatible with low-voltage MCUs (3.3V and 5V). To be compatible with a Raspberry Pi, an ADC converter is required.
This sensor is compatible with the 3-pin "Gravity" interface, meaning it can be directly connected to the Gravity I/O Expansion Shield.
