Soil Moisture Controller

Abstract

Now, aim of research for Soil Moisture Controller to creation. For soil of moisture is maintain one's position be constant. To be censor soil of moisture. If the soil of  moisture to lower form the first setup then the water 'spray to soil. And if the soil  of moisture are equal or more than, to be stop the water's spray. Time duration of censor, determine to millisecond unit. For useful, to be sprinkle avarity of vegatation. In automatic system, Soil Moisture Controller  are made by electronic circuit. For example, transistor switch circuit, h-bridge transistor circuit, basic stamp microcontroller, dot/bar display lm 3914 circuit,  rectifier power supply circuit and voltage regulator circuit.  Conclusion of research, Soil  Moisture Controller be useful for avarity of vegatation such as  farm plants, flower plants, garden plants,  garden tree and small park.
