Monitoring and Control of Vital Parameters in Greenhouse using Internet of Things

Abstract

The purpose of this paper is to design a greenhouse monitoring system (GHMS) which helps the cultivator to monitor environment and control the sensor values by means of feedback mechanism. The methodology involves the combination of six sensors which gives the values of the environment such as temperature, humidity, moisture, obstacle entry, pH and light. The sensor values are analyzed and sent to cloud using Wi-Fi module which enables the online monitoring, displays the values of the sensor in liquid crystal display (LCD) and also send alert mail and messages. The results are obtained and the values are updated in cloud and webpages. This design enables the cultivator to protect the greenhouse environment both online and also offline. In addition to it also gives the alert about any intruder or animals crossing the cultivation area. Thereby the soil parameters, environmental conditions and intruder entry are included in the proposed work. The proposed work of GHMS provides the low cost framework to sense the environment parameters such as temperature, humidity, moisture, light and pH. It also protect the environment of greenhouse from animal attacks using an infrared (IR) obstacle sensor. The sensor values are updated in cloud and messages is sent through Global System for Mobile Communication (GSM) module which is a cost effective one. The need of al-time internet connection is overcome by sending messages.
