ABSTRACT:
A moisture sensitive irrigation control system provides automatic watering of potted plants, lawns, crops, etc. The system utilizes a control valve to effect watering of the soil upon automatic detection of a predetermined level of dryness in a control sample of the soil. The system uses a weight-based method of detecting the amount of moisture in the control sample to regulate the automatic release of a predetermined amount of water into the entire soil for rehydration thereof. As the weight of the control sample increases with the volume of water, the valve is automatically closed to terminate the irrigation process.
