Agriculture is basic source of livelihood People in Bangladesh. It plays major role in economy of country. But now days due to migration of people from rural to urban there is hindrance in agriculture. Monitoring the environmental factor is not the complete solution to increase the yield of crops. There are no of factors that decrease the productivity to a great extent. Hence Automation must be implemented in agriculture to overcome these problems. An automatic irrigation system thereby saving time, money and power of farmer. The Traditional Farm land irrigation techniques require manual intervention. With the automated technology of irrigation the human intervention can be minimized. Continuous sensing an monitoring of crops by convergence of sensors with Internet of things (IOT) and making farmers to aware about crops growth, harvest time periodically and in turn making high productivity of crops and also ensuring correct delivery of products to end, consumers at right place and right time. So to overcome this problem we go for smart agriculture technique using IOT. This Project includes sensors such as temperature, humidity, soil moisture and rain detector for collection the field data and processed. These sensors are combined with well-established web technology in the form of wireless sensor network to remotely control and monitor data from the sensors.

WORKING: Initially the sensor like DHT 11, sun light sensor, Soil moisture sensor capture the data from the filed and is passes to the microcontroller. Now the microcontroller compares the received data with that of pre-existing data and if the values are beyond the threshold point the corresponding devices turns to ON state. Initially temperature inside the farm is compared with that of the pre-defined value in the micro controller and if it is beyond the threshold point then the Motor gets ON. Later soil moisture inside the farm is compared with that of predefined value in the micro controller and if it is beyond the threshold point the alert are sent to the IOT wed page through Wi=Fi module and is represented in a graphical format. After reaching the desired level these devices automatically turns OFF.
