Description: This sensor measures soil moisture to bring some automation to your next gardening project.

When placed into soil, the HUM1100 measures the moisture levels by monitoring the capacitance between its prongs. It outputs a number between 0.0 and 1.0 depending on the moisture of the soil. This sensor is useful for automated gardening projects and environmental research.

This Phidget connects to your computer through a VINT Hub.

Calibration

Generally, the HUM1100 will output values as follows:

0.0 to 0.2 - Dry soil
0.2 to 0.5 - Moist soil
0.5 to 1.0 - Flooded soil

However, the type of soil being monitored can impact these values and each HUM1100 will have a slightly different response so it is important to test for yourself to determine which value corresponds to your desired soil conditions.
