Soil Moisture Hygrometer Sensor Probe kit

This simple soil moisture probe has a trimmer presetable digital output that goes to logic low whenever the soil moisture value exceeds the preset level.

It also has an analog voltage output that generates a voltage in inverse proportion to the soil moisture content. This output then allows the user to estimate the actual moisture content in the soil.

Operating Voltage: 3-5VDC
Analog Output: Voltage at terminal A0. Inversely proportional to moisture content.
Digital Comparator Output: Logic Low when moisture higher than preset.
Probe Type: FR4 PCB

Note: For a more robust and reliable water level probe, you might want to consider using e-Gizmo Water Level Sensor/Soil moisture kit.
