Abstract
The Internet of Things (IoTs) is a network of interconnected devices, transportations, home appliances, and other devices. They are functionally embedded in electronics, software, sensors, actuators, and connectivity that allows them to connect and exchange information. On the basis of the IoT concept, implementations are gradually being proposed in a range of areas, ranging from smart house, smart office and smart agriculture. In this research paper, a generic framework for smart monitoring applications based on the IoTs network is proposed. In this framework, low-powered sensor nodes are based on the micro:bit platform, providing a multiple footprints for different sensor connections. The wireless capability on micro:bit provides a complete solution to deploy the system in such places that wire is impractical to draw. The data is wirelessly gathered by a basestation node that is powered by Android Things operating system provided by Google. This operating system is based on the Android platform for smart devices and Internet of Things products. The approach to this framework indicates a low cost and minimum setup and especially amenable for applications control. To support many applications with minimum modifications, the framework is designed for easy expansion by supporting popular serial connection ports, including the Universal Asynchronous Receiver/Transmitter and Serial Peripheral Interface. With these connections, on one line data bus, several sensors can be added to match the different application requirements. In this paper, our platform is validated for an automatic water monitoring in aquaculture based on the temperature, pH and dissolved oxygen sensory data. Through our framework, the data is uploaded to a cloud for remote monitoring and providing alarms for users whenever the data is out of a predefined safe domain.
Highlights
The Internet Of Things (IoTs) is the key point in the development of Industry 4.0 which is characterized by the generation of device connected network
The fundamental similarity between these applications is the combination of small sensor nodes using low-power sensing devices, a micro-controller embedded in the system, and a transceiver connected in wireless protocol
We present an overview of potential monitoring applications based on the IoTs that is utilized from Wireless Sensor Networks (WSNs)
Summary
The Internet Of Things (IoTs) is the key point in the development of Industry 4.0 which is characterized by the generation of device connected network. The PM must propose plans for the reservation of harvested energy before they are available to guarantee continuous operations Data collection is another issue in monitoring applications based on IoTs. In order to cover such a large area, sensor nodes have to forward their data through many intermediate nodes since the range of the wireless communications is limited (e.g. 30m with radio frequency at 2.4GHz). In this paper, we mainly focus on building a generic IoT platform that utilizes micro:bit boards 30 as a controller in a sensor node and Raspberry Pi 3 running Android Things operating system 31. Android Things and Raspberry PI are proposed for embedded IoTs device, ADC pins are not supported The lack of this feature prevents deploying the system in a wide range of applications, whose sensors normally support ADC outputs. Popular output connections such as VGA, DVI or HDMI are supported by Android Things for visualization the data on a wide screen
