Abstract
The Internet of Things (IoT) has dominated the digital world by enabling thousands of physical devices to communicate with each other and share useful data over the Internet. With use cases spanning every sphere of modern life, the IoT is all set to revolutionize the traveling sector by extending services associated with safety, security, surveillance, tracking, comfort, and a lot more. This paper presents the design and implementation of a prototype Easy-Weigh-Out, based on the principles of the IoT which enables a user to run Android-based mobile application and view the weight of luggage and track its location without any contact with it. The hardware of the system is built around Arduino UNO microcontroller which interfaces with a load cell (20 kg) via A/D converter and a NEO-6M Global Positioning System (GPS) module for tracking of the bag. The system uploads data to a Cloud server using ESP8266 Wi-Fi module. Our results show the real-time weight and tracking of the bag at a click of a button as well as long-term data logging.
Highlights
The Internet of Things (IoT), referred to as the Internet of Everything (IoE), has brought a new era of computing where an ecosystem of discrete computing devices with sensors are connected through the infrastructure of the Internet thereby allowing collection and communication of useful data [1,2]
The Application Programming Interface (API) key generated from the channel was written to Wi-Fi module first, and real time data was visualized on ThingSpeak
It does this by fetching Representational State Transfer (REST) Application Programming Interface (API) data through GET request method, by first setting up a secure Hyper Text Transfer Protocol (HTTP) connection with the server
Summary
The Internet of Things (IoT), referred to as the Internet of Everything (IoE), has brought a new era of computing where an ecosystem of discrete computing devices with sensors are connected through the infrastructure of the Internet thereby allowing collection and communication of useful data [1,2]. The IoT allows connected devices to gather information and analyze it in order to perform a specific task These devices, need to be able to speak to each other to transfer data and share what they are recording. Through investment in the right technology and innovative ideas for use cases comprising of smart features, the IoT has revolutionized the overall travel and tourism industry [6] These features include smarting-locking system, GPS tracking facility, smart-scaling etc. Our Load Cell has a capacity to measure a weight up to 20 kg and we use NEO-6M GPS for longitude and latitude information [8] This real-time data of weight and location is uploaded to an opensource Cloud service ThingSpeak over the Wi-Fi module ESP8266 from where this information is accessed via Android-based mobile application by the end user. The rest of the paper is organized as follows: Section II discusses some of the notable related work, Section III elaborates the hardware design of the system, Section IV provides an insight to the software design, Section V presents the graphical visualization of the results that attest to the usefulness of the system, and Section VI concludes the paper
