Design of a Low-Cost Sensor-Based IOT System for Smart Irrigation

Abstract

The purpose of this chapter is to discuss the design and construction of a smart irrigation system, sensor-based system powered by an IOT (Internet of Things) chip (ESP8266). The design of this irrigation system can be divided into two parts: one is the hardware arrangement which is a low-cost rope and pulley arrangement elegantly designed to cover the crop fields to control the moisture of soil along with other actuators discussed in detail in this chapter, and the other part is an intelligent low-cost IOT-based control system, which can be programmed based on the moisture requirement of a particular crop. The feedback to this control system is sent through moisture, temperature, and rain sensors situated in the crop field, the data of which can also be wirelessly accessed through any open-source IOT platform which can be a desktop or mobile application. The system has also been designed to store the sensor data on a memory card integrated itself in the control system, which is helpful for future research and study of environmental factors on crop production. The system is designed to maintain constant level of moisture in the field by analyzing environmental conditions such as rain or change in temperature of the soil.
