Abstract :
This project is aimed to design a system to Control of Soil Moisture Irrigation System by using Humidity sensor.
Villages are the backbone of our nation. The farmers strive hard day and night to yield very good results in their farm. They know the entire process how to produce a farm, when to provide water to the farms etc. When it is the time to water the farms, they just stop their current works then and there and rush to the farms to start the pump sets to water the farms.
This project provides an excellent solution to this process. The farmer need not go to the farm to water his field. It (motor) automatically gets ON/OFF depending on the moisture level in the field.
This project is designed in such way that a Humidity sensor is interfaced to the controller and along with a motor. The Humidity sensor performs the Task in a manner that it senses the moisture level in the soil. Then the sensor gives the information to the controller, and then the controller gets activated and turns the motor ON/OFF. When the land is in the condition less than the prescribed level the motor automatically gets ON and waters the Field, when the land gets the sufficient water to the indicated level then the Motor gets OFF automatically. If the farmer wishes to water his field, he needs to switch on the motor. Thus, he has to go the field and he has to Switch ON the motor. By using this project there is no need to go the field and switch ON and OFF the motor.
This project uses regulated 5V, 500mA power supply. Unregulated 12V DC is used for relay. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
