Smart Irrigation System using IoT

Abstract

In this work we use drip irrigation where the water was allowed to drip slowly to the roots of plant either from above the soil surface or buried into the surface so that the water can be placed directly into the root zone and minimize evaporation. It uses temperature sensor, soil humidity sensor to collect and monitor field information and also uses float switches to monitor ground water level through web page. When the field gets dry and ground water level falls down it will be notified through SMS. This provides a solution for the problems in developing a smart farming system. It uses node MCU, relay and water pump.

Experimental performance of soil monitoring system using IoT technique for automatic drip irrigation

“…Abioye et al 38 have focused on modeling for environmental parameters that are influencing the irrigation of mustards, whereas Amiri et al 39 have attempted to calculate a suitable position for the soil moisture sensor in a drip irrigation system for a particular application and an area in the soil profile representative in the root zone. Gayathri et al 40 have attempted to develop smart drip irrigation using IoT where the water is allowed to drip gradually to the roots of plants so that the water can reach directly into the root zones and reduce evaporation in the environment. Pradeep et al 41 have attempted sensor‐based IoT technology for smart irrigation which gathers the humidity, soil moisture, and temperature data and transmits this information to the farmers of irrigation systems.…”
