Origin:CN(Origin)
Model Number:Soil Moisture Detector Module
Output:DC3.3-12V
Voltage: DC3.3-12V
Size: 36*15*7mm
Current: working
Interface: +-DO AO
Uses: check soil moisture
Principle: The soil moisture probe detects the humidity, and the voltage comparator determines the humidity. When the temperature is greater than the set value, the DO output is low.
