IoT-based real time greenhouse monitoring and controlling system

Abstract

With the ongoing rise of social and economic levels, as well as people's living standards, the demand for out-of-season vegetables and fruits has increased in recent years. Nowadays, advanced scientific technologies are increasingly applied to traditional agricultural production. With the aid of Internet of Things (IoT) applications, intelligent greenhouses have helped cultivate growth. Intelligent greenhouses can produce a proper growing environment for crops, improve crop yields and quality, and achieve efficient production output. Temperature, humidity, and other elements are the key factors impacting crop development in greenhouses; how to effectively measure and control these environmental parameters is critical for farmers. In this study, an IoT-based, low-cost, intelligent agricultural production environment monitoring system is designed and developed. This system could monitor interior ambient temperature and humidity in real-time through the DHT22 sensor, and the collected data is stored in the ThingSpeak cloud. In addition, a fan and a heating panel are utilized to control the inside environment. The results showed that the environment would be constantly adjusted and maintained at an ideal level for crop growth.
