Sensor for measuring soil moisture HD-38

Product detailed description

A module for detecting soil moisture, which can be used to create, for example, an automatic watering system for flowers in the home. When there is not enough water in the soil, the module gives a logic 1 signal. The trimmer can be used to adjust the sensitivity of the LM393 comparator. It also has an analog output.

This version should be an improvement mainly in the technical design - the contacts should not be subject to corrosion as fast as other sensors. When measuring soil moisture, the conductivity of the soil is measured - i.e. the current passes from the first electrode through the soil and plant to the second electrode.
