Internet of Things Based Smart Greenhouse: Remote Monitoring and Automatic Control

Abstract

Conventional greenhouses need regulated climate conditions to grow plants in there. Without an automatic control system, it is quite impossible to maintain the accurate climate conditions inside the green houses. This paper proposes such an automatic system for greenhouses to control its' internal environment, to store each climate properties in a database for future analysis and to ensure remote monitoring to those data. Internet of Things (IoT) is used for remote monitoring and analysis of data. Also, an android application is developed to display those data in a short range through Bluetooth technology.The system controls the temperature, humidity, light and soil moisture level by sensing the values from sensors and controlling heaters/coolers, sprayers, bulbs and water pumps accordingly.

Estufas Inteligentes e Eficientes Energeticamente: uma análise descritiva da literatura

“…Em seu estudo, Ullah et al (2018) conceituam a IoT como uma fusão entre o mundo físico e objetos até então inanimados com o mundo computadorizado, automatizando tais objetos. Os autores (2018, p. 1) prosseguem na caracterização dessa nova tecnologia, pontuando que a IoT "[...] pode ser expressa como a arquitetura de coisas físicas implantadas com circuitos eletrônicos, sensores e programação, juntamente com um sistema associativo que permite que essas coisas troquem informações entre si", concluindo que a rede 5G dará uma propulsão considerável ao arranjo entre coisas e internet.…”

“…A IoT proporciona detecção, mensuração, tomada de decisões e controle de outros dispositivos remotamente sobre a base de um sistema existente que faz o gerenciamento dos dados e ações de forma autônoma e inteligente, criando uma inter-relação entre os objetos ou sistemas sem que seja necessária intervenção humana (ULLAH et al, 2018).…”

Modular architecture of an automated process control system in greenhouse complexes

“…To transfer data between the controller and the server, the GSM-GPRS technology is used 8 , which is reliable and fast. For remote monitoring and analysis of data from sensors installed in the greenhouse, the proposed system uses the concept of the Internet of Things (IoT), which, according to its authors, is the most promising technology for connecting field devices to wireless Internet networks or to devices with remote control 9,10 .…”

A remote manipulator control system based on a programmable logic controller and internet of things technology

“…According to the requirements of palletizing system, the remote control of remote control robot is realized by using programmable controller and Internet of things technology [4]. The system can realize remote direct control and local control of palletizing robot.…”
