Hydroponics System for Soilless Farming Integrated with Android Application by Internet of Things and MQTT Broker

Food, water and land, are the most essential resources to mankind, and these three resources are dependent on each other. Without proper soil or land and proper quantity of water, one cannot produce a healthy batch of crops. This is the problem of the current age due to lack of quality water and land. Climate change also affects the quantity and quality of the yield which, in coming years, may directly affect the economy of a country directly. Many countries may suffer from economical crisis due to lack of food production. A solution is needed to preserve the water resources and to maximize the profit per square feet of land which will help in production of higher quality and quantity yield, and directly or indirectly, profits the farmer or economy of the country or region. Hydroponics is such a system for farming which uses only water and nutrients for growing most terrestrial plants without the use of soil. Hydroponics can be implemented in urban location but it requires prerequisite knowledge and regular monitoring. To solve the above problem, automatizing of the entire process with sensors and micro-controller has been reported in this paper. Here an IoT based hydroponics system parameters are monitored via Android application. This will further help for improvement in system based on data generated from multiple hydroponics farms.
