Greenhouse Farming using IoT

Abstract

The most frequent problems faced in Greenhouse Agriculture is pH changes, Watering and Temperature. Plants need light, carbon dioxide and mineral nutrients in order to produce food and grow. Water is supplied through substrate, and it contains dissolved mineral elements. The mobility of these nutrients is determined by pH. A pH reading is measurement of the acidity or basicity of solution. The goal of a greenhouse grower is to maintain stable pH over the life of crop. In greenhouses, in case of insufficient or poor ventilation of greenhouse, the crops may be attacked by diseases. There may be extreme and sudden temperature changes. Moreover, it is not good to have regular watering routine for crops in the greenhouse, but neither it is not good to let plants dry. Hence sunlight, moisture and pH of soil plays vital role in greenhouse agriculture. To overcome these problems an IoT device which can give suggestions about when to water, adjust pH and change lighting for plants in greenhouse to improve the production. The goal is to increase the yield and reduce the complexities in organic farming for the farmers.
