Capacitive soil moisture sensor Corrosion Resistant wide voltage wire for arduino

This Capacitive Soil Moisture Sensor V2.0 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 can be directly connected to the Gravity I/O expansion shield.
