This sensor measures the volumetric content of water inside the soil and gives us the moisture level as output. This soil moisture sensor measures soil moisture levels by capacitive sensing rather than resistive sensing like other sensors on the market.
Includes an onboard voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5 V. Measures soil moisture levels by capacitive sensing. Analogue output, insert it into soil and feedback with the real-time soil moisture data. Supports 3-pin gravity sensor interface
