ABSTRACT:
The project is intended to build up an automatic irrigation system which switches the pump motor ON/OFF on sensing the moisture content of the soil. In the field of horticulture, utilization of legitimate strategy for irrigation is important. The advantage of utilizing this technique is to lessen human intercession and still guarantee legitimate irrigation.
The project utilizes an 8051 arrangement microcontroller which is customized to get the information flag of varying moisture condition of the soil through the sensing arrangement. This is accomplished by utilizing an operation amp as a comparator which goes about an interface between the sensing arrangement and microcontroller.
Once the controller gets this flag, it creates output that drives a transfer for working the water pump. A LCD show is additionally interfaced to the microcontroller to show status of the soil and water pump. The detecting course of action is made by utilizing two solid metallic bars embedded into the field at a separation. Associations from the metallic bars are interfaced to the control unit.
