IOT Based Smart Irrigation System Using Node MCU
Abstract
The Internet of Things (IoT), the idea of getting real-world objects connected with each other, will change the way users organize, obtain and consume information radically. Internet of Things (IoT) enables various applications (crop growth monitoring and selection, irrigation decision support, etc.) in Digital Agriculture domain. The Wireless Sensors Network (WSN) is widely used to build decision support systems. Irrigation plays an important role for development in food production. Farmers are using traditional methods of irrigation for farming and a large amount of water is getting wasted due to these methods. These outdated techniques have to be replaced with automated technique. Internet of Things (IOT) is a milestone in the evolution of technology. IOT plays an important role in many fields. The irrigation system, which works based on the latest IOT technology to reduce the wastage of water and it also, reduces manual work to irrigate the crops. Sensor is used to take sensor reading like soil moisture, Humidity Sensor and decision making is controlled by user (farmer) by using NodeMCU. The data received from sensors are sent to server database using wireless transmission. The irrigation will be automated when the moisture and temperature of the field is reduced. The farmer is notified with the information regarding field condition through mobile periodically. This system will be more useful in areas where there is scarcity of water.
