Smart Water Management in Irrigation System Using IoT

Abstract

India is a wide country, where people mainly do agriculture for their living. This is the most important earning source for most of the Indian families residing here. Agriculture in India contributes to about 13% of total exports, 6% of total industrial investment, and 16.5% of total GDP. The main resource to continue agriculture in the country requires water resources. Irrigation can help in this area but there will be wastage of water in some way or the other. Many of the farmers usually supervise on a widely spread area for farming activities which becomes very difficult to manage and keep track of every corner. Sometimes, there are cases of uneven water sprinklers. This leads in bad production which results in financial losses of farmers (Pandit in IoT based Smart irrigation system using soil moisture sensor and ESP8266 NodeMCU, July 15, 2019, [1]). Automation of the activities required to carry out irrigation will reduce the need of human supervision or intervention, which will lead to transforming the system from static and manual to dynamic and intelligent which will, in the end, result in higher production (Hariharan in Int J Emerg Technol Innov Eng 5(3), 2019, [2]). The modern irrigation systems like the drip irrigation system and the sprinkler irrigation system need to be combined with the Internet of Things (IoT) for better productivity in agriculture activities and efficient water usage. This task aims at monitoring parameters for soil like, soil moisture, humidity, and temperature while also regulating and monitoring the water level of the water tank. Smart irrigation system will improve crop fields while also saving water. Smart irrigation system can be used to control greenhouse. The system uses wireless sensor network to detect and control the different parameters dynamically in real time for efficiently managing and maintaining the whole system.
