IoT based Smart Irrigation System

An embedded system is a special purpose computer system designed to perform a dedicated function. Since the function is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product. Embedded system comprises of both software and hardware. Embedded system is fast growing technology the application of Embedded system is vast a PC or a controller is used to do the specified task the controller is programmed using assembly or Embedded language like Embedded C. Many devices are used for monitoring the humidity conditions. In early days, all the systems are analog devices and the measured value can be displayed by using recorders and CROs. This project is used to eliminate the drawbacks in the existing system. Here the humidity is monitored by sensor that can be converted in to corresponding signal to the microcontroller other sensors are also used to expand the capability of the system by sensing the environment conditions. The main feature of this project is that, according to the moisture levels, the controller activates the relay driver unit and pumps motor by using relay switches [21]. The controller receives reading from all sensors and uploads the readings to the cloud using esp8266 Wifi module. And the same readings of sensors as well as the pump status can be seen in the android App. App can even control the system remotely from anywhere in the world.
