Automated Plant Irrigation System using Arduino

Nowadays, farmer are facing lots of problems regarding unavailability of grid in rural areas. So the solar energy is the best option for farmers to water their fields and keep plants healthy. Also watering to plants must be done properly so that plant does not get overwater or the less water with the help of soil moisture sensor. Sometimes plants get extra water which will cause them to rot. And also due to less water or no water, plants get burned. So plants needed to be supply the particular amount of water neither less nor more. Keeping in mind we have design the system which will provide the water to the plants when the soil get completely dry and automatically stops the motor when soil get wet. The condition of soil will be observed by the soil moisture sensor and the plant watering will be done by the sprinkler arrangement. According to the decided area and according to the sprinklers water throwing capacity, number of sprinklers was connected. Tank level sensors are also used to avoid the wastage of water after tank is full. Temperature also displayed on the LCD display. This project uses the ATmega328 microcontroller.
