    Description
    Planning for auto gardening project? You might need this moisture sensor to detect moisture of your soil further control the pipe valve to water your plants :)

    This sensor comes in 2 parts, sensor probes and module board. The sensor is basically two probes to be inserted into soil. This sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance).

    The module come with a comparator and adjustable potentiometer for user to adjust the threshold to toggle digital output. You can choose to use the digital or analog output.
