ABSTRACT
Irrigation is the art of applying water to the plants/ fields to grow and to increase the quantity as well as quality of the fruits, food grains etc., Automatic irrigation system is a modern method of irrigating the vegetable, fruit fields, farms, gardens and land scraping areas as against the conventional method, which uses large number of men- hours and uncontrolled water quantity. This modern irrigation method using soil sensors (copper electrodes) has the advantage of precisely applying water for irrigation in both location and point, thus offering the potential of increased profit due to reduced water.
This project work describes about “Automatic Plant Watering System” designed with Arduino microcontroller. The main purpose of the project work is to apply water to the plants automatically, by sensing the soil condition. For sensing the soil condition, weather it is dry or wet, two copper electrodes are used as soil sensors for two fields and output of these sensors are fed to the microcontroller. The output of microcontroller is used to drive the relay to operate or control the pumping motor to the field whose soil is dry. This is electrically controlled equipment, when the soil is found to be dry; automatically the controller moves the pumping motor to that particular field and energizes the relay to activate the water pumping motor and supply water to the field or plants.
And when the motor is switched ON the soil condition becomes wet. By sensing the wet condition of the soil, automatically the pumping motor will be switched OFF by the microcontroller. Thus, saves precious water and electricity as well. A small proto type module is constructed for practical demonstration of the concept. The demo module is constructed with two fields and these are identified through magnetic and limit switches arranged at the fields. The DC water pumping motor is arranged over the sliding channel mechanism moves horizontally between the fields.
