This 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 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 Pi, it will need an ADC converter.
