Agriculture Pump Control

AGRICULTURE BASED WET AND DRY CONTROL FOR PUMP FROM REMOTE DESTINATION

ABSTRACT:

The main aim of this project is to identify the water availability condition to the soil and to automatically control the water supply to the land in order to prevent the dry run condition of for the soil. In this project we use embedded technology to indicate the status of the soil. In order to achieve the good profit in the agricultural field the soil should be maintained in proper condition that fits for the crop cultivation. The main thing that should be seen in order to achieve the profit is to maintain the wet condition of the soil in the correct proportion.

The manual work to achieve the above condition is critical so we have decided to do this project with the help of embedded technology using PIC microcontroller. In this project a humidity sensor is used to sense the wet condition of the soil. The water level in the foil is sensed by using water level sensor.

The sensed condition is given as the input to the PIC microcontroller and based on the condition is given as the input to the PIC microcontroller and based on the condition the PIC microcontroller will give the signal to relay which drives the pump and to mobile phone which displays the condition of the soil.

If the sensed condition is found to be dry the “SOIL IS DRY” will be get displayed in the mobile phone and simultaneously the relay will TURN ON the pump in order to wet the soil.

If the sensed condition is fount o be wet the “SOIL IS WET” will be get displayed in the mobile phone and the signal to the relay will be given in order to TURN OFF the pump to stop the water availability to the soil.

The main advantage of this project is the soil maintenance can be achieved effectively and the water supply to the soil can be provided without any interruption.
