This Capacitive Soil Moisture Sensor measures soil moisture levels by capacitive sensing, rather than resistive sensing like other types of moisture sensors. A capacitive Soil moisture sensor is made of a corrosion-resistant material giving it long service life. Insert a capacitive soil moisture sensor into the soil and impress your friends with real-time soil moisture data! The product includes an onboard voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V. It is compatible with low-voltage MCUs (both 3.3V and 5V logic). To make it compatible with a Raspberry Pi, an ADC converter is required
