    I have just built the datalogger Picaxe 18X datalogger (kit number AXE110).
    It seems to be working as it should with the temperature and light sensors
    that came with the kit.

    Now I want to add a soil moisture sensor to the datalogger. The purpose of
    the setup will be to determine if a patch of garden needs to be watered, so
    accurate measurement of the soil moisture content should not be necessary. A
    sensor which could tell the difference between "damp", "wet" and "dry" soil
    would probably do fine. Even a sensor which could tell the difference
    between "wet" and "dry" would be a start.

    Does anyone know what can be used as a soil moisture meter with this kit?

    Thanks for any assistance
