Soil Hygrometer Humidity Detection Moisture Sensor
The soil moisture sensor can be used to detect moisture, when the soil is dry, the module outputs a high level, whereas the output is low. Using this sensor make an automatic watering system so that your garden plants without people to manage. The soil moisture module is most sensitive to ambient humidity is generally used to detect the moisture content of the soil. Module to reach the threshold value is set in the soil moisture, DO port output high, when the soil humidity exceeds a set threshold value, the module D0 output low.
Features
- Dual output mode, analog output more accurate
- A fixed bolt hole for easy installation
- With power indicator (red) and digital switching output indicator (green)
- Having LM393 comparator chip, stable.
