One of the essential and basic services to survive on earth is Water. Recent time increasing the scarcity of water due to growing in population. So this is becoming as a universal obstacle. These days, in the agriculture sector farmers are facing major problems regarding irrigation. Due to over- irrigation and under-irrigation, the crops can be damaged. The old irrigation system which demands a lot of water, so it needs smart techniques for reducing the percentage of wasting available water for the irrigation. We have been seeing the increasing of huge demand for Internet of things in every domain from small and simple applications to large and complex applications. Practically implementation of a Smart Irrigation is very complex deal, but association with IoT using Smart wireless sensors it brings a great management system. The Humidity and Temperature Sensor sense the both water vapor content and temperature around the plant. The Soil Moisture Sensor sense the soil moisture of a plant, if water content is below minimum requirement then water will supply from water reservoir using relay and water level sensor sense the water level of reservoir after that sends the data to Arduino Nano and  it is a Microcontroller gets the data from smart wireless sensors, process the data and control tasks of water pumping .

The above is our proposed block diagram for smart irrigation. The system mainly contains the microcontroller that is Arduino Nano. To measure various parameters this affects the plant growth and helps to analyze the amount of water requirement for plant. We are using soil moisture sensor which will detect the moisture content in the soil. Temperature and Humidity sensor will detects the temperature and humidity. The water level sensor is used to know the water level. All these sensors will continuously sends the data to the Arduino microcontroller and the controller will collects there sensors data and analyze the data. The controller after analyzing the sensors data turn on the relay which in turn on water pump to provide required amount of water to the plant.

These days, in the agriculture sector farmers are facing major problems regarding irrigation. Due to over- irrigation and under-irrigation, the crops can be damaged. The old irrigation system which demands a lot of water, so it needs smart techniques for reducing the percentage of wasting available water for the irrigation. We proposed a smart irrigation system using Arduino Nano microcontroller. The system will automatically provide only required amount of water to the plants after analyzing different sensors data which affects the plant growth.
