This Capacitive soil moisture sensor measures soil moisture levels by capacitive sensing rather than resistive sensing like other sensors on the market. It is made of corrosion-resistant material which gives it excellent service life. Insert it into the soil around your plants and impress your friends with real-time soil moisture data!
This module includes an onboard voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V. It is perfect for low-voltage MCUs, both 3.3V, and 5V. For compatibility with a Raspberry Pi, it will need an ADC converter.
This soil moisture sensor is compatible with our 3-pin “Gravity” interface, which we can connect to the Gravity I/O expansion shield.

  3. Intelligent agriculture
Note: This module is available in different versions. The V1.2 version sensor can work with only 5v while the V2.0 version sensor works with both 3.3V and 5V
