This paper designs a model of automatic irrigation system which is based on microcontroller ATMEGA328. Temperature and soil moisture sensors are placed in the field. Sensors sense the moisture content of the soil and give the information to farmer through GSM Module. In the conventional system the components like motor, main valve A , control valve B needed to be controlled manually. As, we want to implement automization these components need to be controlled automatically with the help of PLC depending upon the program fed in it. Also, for this a climatic criterion is required to control the Irrigation system controls valves by using automated controller allows the farmer to apply the right amount of water at the right time, regardless of the availability of the labour to turn valves. Some irrigation systems are used to implement efficient irrigation scheme for the field having different crops. The system can be further enhanced by using fuzzy logic controller. The fuzzy logic Schematic Circuit Diagram of Automatic Plant Watering & Irrigation System. According to this system there are two functional components in this project i.e. Moisture sensor and motor/water pump. In its most basic form moisture sensor senses level of the soil moisture. Then motor/water pump supplies water to plants. Click image to enlarge. In automatic irrigation module the water outlet valve of the tank is electronically controlled by a soil moisture sensing c ircuit. The sensor is placed in the field where the crop is being cultivated. The sensor converts the moisture content in the soil into equivalent voltage. automatic systems to control water usage in order to reduce much of the wastage. Irrigation is an artificial application of watering the land for agricultural production. The requirement of water for soil depends on soil properties such as soil moisture and soil temperature. Effective irrigation can influence the entire growth process and automation in irrigation system using modern technology 2.5 Sensor-based Automatic Irrigation System This system also depends on the measurement of soil humidity and temperature. The system works by sending a signal from farm controller to user phone and it phone must be in automatic reply in case that soil needs water. a signal from phone send to farm controller again to switch on or off the system.

These two approaches are bypass and on-demand, respectively. An automation of irrigation systems
