Soil Moisture Sensor with 1.3M Corrosion Resistance Probe
Soil Moisture Sensor Soil Detector Module Soil Moisture Test Soil Humidity Test with 1.3M Corrosion Resistance Probe for Arduino
Interface: +-DOAO DO digital/AO analog
Uses: Detecting soil moisture
Principle: The soil humidity probe detects the humidity, and the voltage comparator judges the humidity.
1. Connect the positive pole of the power supply and the negative pole of the power supply.
2. Clockwise/counterclockwise adjustment of the blue potentiometer can improve/decrease the detection sensitivity of the probe.
3. The potentiometer is clockwise adjusted to the output indicator of [S], it indicates that the range of regulation has exceeded the test threshold, and when the counter-clockwise adjustment is unable to adjust, it exceeds the threshold. When adjusting, they should not exceed the threshold value, otherwise, they can not be used normally.
4. A single-chip computer can directly detect the analog (voltage) output of an Analog Output (AO) through its port.
Please manually measure to allow for differences of 1-3cm.
