Description
This sensor measures the moisture levels in soil by using capacitive sensing, which is different from the resistive sensing method that other sensors use. It is made of a material that resists corrosion and lasts longer. You can insert it into the soil near your plants and show your friends the real-time data on soil moisture!
This module has a voltage regulator that allows it to work with a voltage range of 3.3 ~ 5.5V. It is suitable for low-voltage MCUs, both 3.3V and 5V. You will need an ADC converter to use it with a Raspberry Pi.
This soil moisture sensor can connect to our 3-pin “Gravity” interface, which you can plug into the Gravity I/O expansion shield.
