Greenhouse Monitoring and Automation Using Arduino: a Review on Precision Farming and Internet of Things (IoT)

Abstract

The 21st century became the beginning of the development of information technology, where one of the revolutions was the presence of the Internet of Things. Internet of Things or abbreviated as IoT is a technology that combines electronic devices, sensors, and the internet to manage data and applications. The Internet of Things can be adopted in agriculture for crop management as a media for monitoring and controlling, especially in greenhouses and is called Precision Farming. The application of precision farming will be more effective in a greenhouse because it is easier to engineer similar environmental conditions. IoT development in greenhouses is using Arduino Microcontroller or Raspberry Pi Microcomputer. These devices are used because the price is low and easy to get on the market and can be designed so that technicians who have limited information technology knowledge can run it. To be able to manage greenhouses with IoT requires sensors as five senses that can detect changes that occur in the greenhouse. By using sensors, the hardware can detect what is happening in the greenhouse and make decisions based on the data acquired. Some sensors that are often used in Precision Farming are temperature and humidity sensors, soil moisture sensors, and light sensors. In the Internet of Things, the data that has been acquired by the hardware will then be transmitted wirelessly. The wireless connections used are Bluetooth, ZigBee Protocol, and Wi-Fi, where Bluetooth and Zigbee connections have a short distance between 10-100 meters, while Wi-Fi has a longer distance especially when connected to the Internet. The purpose of this paper is to understand the advantages and challenges of adopting IoT-based Precision Farming for monitoring and automation.

Internet of Things Based Cutting Tool Status Monitoring in a Computer Numerical Control Milling Machine

“…IoT grows with Arduino microcontrollers or Raspberry Pi microcomputers in greenhouses. In addition, Bluetooth, ZigBee, and Wi-Fi are used [28]. For IoT Smart City applications, this paper proposes to apply deep learning techniques to identify botnets.…”

Impact of Soil Water Quality on Yield, Qualities and Water Consumptive Use of Melon (Cucumis Melo L)

“…Applied of soil water as source irrigation for melon combined with the autopot may could efficient of water consumptive use and increase quality and yield of melon; because crops are protected from diseases and are kept healthy [10]. The combined system of fertigation and autopot is a new alternative system used to increase melon production.…”

Application of Internet of Things in Smart Greenhouse Microclimate Management for Tomato Growth

“…Application of the Internet of Things (IoT) in a smart greenhouse using a mist cooling system expected could change extreme temperature and humidity to the optimum potential for tomato growth; it is to solve problems found in plant growth, especially found in tomato hydroponic cultivation [10]. Protected plant growth is usually favorable to sustainable microclimate and realizes its maximum production even than the need for various environmental conditions [11].…”
