Abstract: This paper cover the design of fuzzy irrigation system based on AVR microcontroller Atmega 32 to design and develop a low cost feature which is based on embedded platform for water irrigation system. The project designed using MATLAB 10, fuzzy logic and Simulink tools books the temperature and soil moisture sensors are used for detect the water quantity present in agriculture and water level sensor used for detecting water level in tank the level gauge interfaced by electronic circuit worked as signal conditioner circuit the water from tanks controlled by solenoid valve which actuated by relay circuit open and close as the microcontroller output then the water transmitted to roots zone using pipes line for irrigation process . The data from plant farms transmitted to control room by wireless networks in which temperature and soil moisture sensors and water level can be monitored and controlled.
