Soil moisture sensor with a module that includes a built-in voltage regulator in the range of 3.3-12V. The probe is made of corrosion-resistant materials, which significantly extends its service life.
DO: digital output
AO: analog output (voltage)
The soil moisture probe detects the temperature and the voltage comparator assesses the moisture, when the moisture is greater than the set value, DO sends a low level.
