Abstract
A functional smart irrigation system with integrated GSM and Wi-Fi features that enables the farmer to remotely check soil moisture status as well as turn on and turn off the irrigation pump remotely, where necessary had been developed in this study. The system consists of a DC pump, a GSM module, moisture sensor, and the NodeMCU microcontroller. The prototype is essentially a mix of hardware module and software program and made up of several subunits. It behaves functions intelligently as a switching system being able to detect the moisture content level of the soil and then automatically irrigate the crop where the conditions are necessary. The motor is automatically turned ON or OFF in accordance with the soil moisture content level. The readings of the soil sensor are sent to a processing unit which generates graphs for analysis thereby helping the farmer make informed decisions.
