DESIGN AND FABRICATION OF AUTOMATIC CONTROL OF RAINGUN

In daily operations related to farming or gardening, Watering is the most important cultural practice and the most labour - intensive task. No matter whichever weather it is, either too hot and dry or too cloudy and wet, you want to be able to control the amount of water that reaches your plants. modern watering systems could be effectively used to water plants when they need it.But this manual process of watering requires two important aspects to be considered.when and how much to water. In order to replace manual activities and making gardener's work easier, we have created automatic plant watering system by controlling the rain gun with the help of sensor data. By adding automated plant watering system to your garden or agricultural field, you will help all of your plants reach their fullest potential as well as conserving water For implementation of automatic plant watering system, we have used combination of sensors like humidity, ultrasonic, PH, fire sensor, pipes, and rain gun. This project uses the Arduino micro controller, it is programmed to sense moisture level of plants and soil at particular instance of time,if the moisture content is less than specified threshold which is predefined according to particular plant's water need then desired amount of water is supplied till it reaches threshold. Generally, plants need to be watered twice a day, morning and evening. Thus, the micro controller is programmed to water plants two times per day. Ultra sonic sensor senses the height of the crops, which also controls the pump. In addition to the above, PH sensor is installed for monitoring the condition of soil as well as for detection of fire disaster fire sensor is alsoincorporated in this system. We hope that through this prototype we all canenjoy having plants, without being worried about absent or forgetfulness.
