Design and implementation of a smart irrigation system for a sustainable water management in Niger

Abstract

A smart irrigation system with less human intervention has been designed and implemented. A statistical data analysis was conducted on the evolution of climate factors that affect the irrigation in Niamey such as temperature, relative humidity, wind speed and rainfall. This analysis has revealed an increasing temperature from 1986 to 2020. But during the same period, the other parameters are decreasing with a high variation of rainfall. As a result, a growing need of irrigation in the area of study has been observed. To develop the proposed irrigation system, we made use of an Arduino microcontroller, a relay, a temperature and humidity sensors, a soil moisture sensor, a motor pump with three drip irrigation pipes and a breadboard. The system has been experimented on tomato nurseries.
