Abstract

The purpose of this work is to make an IoT-based low-cost and power-efficient portable system to control irrigation using a threshold value algorithm and to measure soil-irrigation-related parameters such as soil moisture, soil temperature, humidity and air temperature.Design/methodology/approachThis paper presents a threshold value algorithm to optimize power consumption and to control irrigation process.FindingsThe system uses ESP-12F 8266 as the main microcontroller unit to monitor and control irrigation system. The system also consists of an actuator system that triggers automatically based on a threshold value algorithm. An open-source cloud platform is used to monitor and store all the data for future perspective. To make the system run for a long time without any human intervention, a solar panel is used as an alternate source of energy for charging the 12V lithium-ion battery. The battery takes 2.64 h for full charging considering peak intensity of sunlight.
