Smart irrigation system based on internet of things (IOT)

Abstract

Nowadays, the Internet of Things (IoT) technology is very much used in agriculture. Therefore, this paper is about a project that focuses in the field of agriculture with the objective of controlling the water consumption in agriculture field which is based on IoT where all information is viewed and controlled in fingertips. As a part of the system development, few sensors applied such as: (i) a soil moisture sensor (YL-69) to detect the water level in soil; (ii) the humidity and temperature sensor (DHT-11) to trace early signs of temperature changes; and (iii) the pressure sensor (BMP 280) to measure the pressure of the surrounding. These sensors are connected to a Wi-Fi module (Node MCU) and they are interdependent to give extra sensitivity to the irrigation system. The data collected will be uploaded to the cloud (ThingSpeak.com and Firebase) and displayed in the form of graphs that could be seen through the app and website. The app functions to display the reading from the sensors and to control the water pump for emergencies purposes. In conclusion, the project managed to fulfil all its objectives in the aspects of water consumption, minimal project cost, less labour, power consumption, and reliability.
