A system for automatically controlling a lawn watering system responsive to the moisture content of the soil includes at least one moisture sensor which supplies a signal to a moisture controller to actuate a water supply valve. The moisture sensor has a casing containing two electrodes and an insulating body of synthetic fibers which provide a path to transfer water from the soil to the electrodes.
