Introduction
Our soil moisture sensor measures soil mositure levels by capacitive sensing rather than resistive sensing like other sensors on the market. It is made of corrosion resistant material which gives it an excellent service life. Insert it in to the soil around your plants and impress your friends With real-time soil moisture data! This module includes an on-board 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 Pis will need an ADC converter. This soil moisture sensor is compatible with our 3-pin Gravity interface which can be directly connected to the Gravity I/O expansion shield.
