Over a past few years, technology is constructing the way humans live. With the rapid growth towards Internet of Things (IOT) and other connected services, companies are investigating the ways to enhance current living conditions. There are several devices that are launched in the market to help people to increase flexibility and most of all, to see beyond what is possible. It is helping us reinforce ourselves in our day to day activities. Even in sports, thanks to the latest technological developments, most people’s lives have been enhanced and simplified. Advances in technology has a huge impact on sports which includes- analysis of sport performance, improvements in design of sports equipment and facilitate coaches to provide feedback on players’ performance. Sports equipment continually undergoing research and development to improve sporting performance ensuring a superior game and positive results. Significant technology such as smart gear is popular among athletes to analyse their performance. The equipment usually includes sensors controlled by microcontrollers. The main contribution of this thesis is to investigate the possibilities of a suitable sports equipment to detect and calculate speed of a fast-moving object and providing the drawbacks while using different sensors. In this thesis, IR/Laser sensors, along with a Doppler radar module were tested to put forward a best suitable method to calculate the speed of a fast-moving object and transmit the data over a network.

In the following chapters a overview of components, design of circuits, practical realization and test of whole system.

Syftet med arbetet var att konstruera internetuppkopplade vågar till Södersjukhusets förråd som kan notifiera när påfyllning av batterier och elektroder till defibrillatorer behövs. Vågarna konstruerades av lastceller med förstärkare, och med utvecklingsmiljön Arduino kunde de programmeras för att skicka vågarnas värden till olika webbsidor som sköter notifieringen. Resultatet blev att vågarna skickar mejl när valda gränser har uppnåtts. Batterier och elektroder är viktiga för defibrillatorers funktion, vilket kräver ständig kontroll av Södersjukhusets medicintekniska personal att dessa finns tillgängliga. Slutsatsen är att vågarna har konstruerats och kan notifiera vid bestämda gränsvärden. Dessa gränsvärden utgörs av vågarnas värden som visas för ett batteri och ett elektrodpaket till en defibrillator.

This thesis focuses on the design and implementation of a new, inexpensive, and less complex system for a Do-It-Yourself (DIY) Internet of Things (IoT) platform. The hardware aspects focus on a new chip called the ESP8266 which contains both microcontroller and WiFi connectivity capabilities in an extremely affordable package. The system uses the Arduino IDE to program the ESP8266, which is known to be an extremely user-friendly environment. All other software is both free and easy to use. Past methods of creating IoT projects involved either expensive hardware, often ranging from $50-$100 per node, or complicated programming requiring a full computer, or a constant connection to an immobile power source. This method costs as little as $2.50, can last for months or even years off of batteries, can be smaller than a quarter, and only requires a few lines of code to get data moving, making this platform much more attractive for ubiquitous use.

The work described in this thesis is aimed at comparing Raspberry Pi model 3 B and Arduino Uno with an ESP8266 wifi module to see which one is most suitable to use in a Internet of Things project where data collecting from an sensor, processed and then presented. The method for this comparison is to divide the work. First, price and power consumption will be evaluated. Then, the stability of communication over wifi will be tested. Finally, the time it takes to design a program on the platforms will be measured. The result from the comparison show that the Raspberry Pi is the best choice for this type of Internet of Things projet. However, which platform to choose depends on the specific goals of the project since the platforms are good at different things. A server written in Python communicates with the Raspberry Pi by using socket to socket communication, the Raspberry Pi collects the data from the sensor and then sends it to the server. The server then saves the data in a database by the unit identification number. Then a webpage was designed that presented the data to the user. A usabiity test was done on the webpage and the result from the usability test showed that the test users was satisfied with the usability with the page, exept the choice of colors, which was fiexd. / Arbetet beskrivet i detta examensarbete går ut på att jämföra vilken av plattformarna Arduino Uno med en ESP8266 wifi-modul och Raspberry Pi 3 modell B som är mest lämplig att använda i ett Internet of Things projekt där inhämtning av data, bearbetning av data och presentation av datan. Metoden för arbetet är att dela upp det i olika moment, först undersökt faktorerna pris och strömförbrukning därefter testas kommunikationen över wifi för de olika plattformarna och därefter hur lång tid det tar att skapa ett test för kommunikationen på varje plattform. Resultatet av jämförelsen är att Raspberry Pi är mest lämplig för detta projekt, men att avgöra vilken plattform som ska användas i Internet of Things beror till störst del på vilka krav som finns, eftersom bägge plattformarna har sina egna fördelar mot varandra. En server skriven i python hämtar datan från sensorn via Raspberry Pi med hjälp av socketmeddelanden, därefter sparas datan i en databas där ett identifieringsnummer för plattformen styr sparandet av datan. För att kunna presentera datan från sensorn så skapades en webbplats som hämtar datan från databasen beroende på om användaren skickar en begäran från webbplatsen. Ett användartest har genomförts på webbplatsen för att undersöka användbarheten. Användartestet visade att webbplatsen hade de funktioner som användarna ansåg behövdes, enda åtgärdspunkten var färgsättning på webbplatsen som åtgärdades.

Sinkholes are hazardous to buildings and their occupants, so a sensing device that can monitor underground changes is vital. Void Technology, developed in the Research and Development Center at Western Kentucky University, is creating a device that can improve monitoring for any movement underground. This device, created by Void Technology, is equipped with ESP8266, which is a Wi-Fi module that can send its information to the router in a wireless network. The focus of this thesis is on designing and developing an IOS framework application to show the signal strength capabilities in different buildings to find the optimum placement of the Void Technology devices. Each building, based on various construction materials, had different attenuations that could cause signal loss from the application to the ESP82266. The optimum place was found with this designed application. From this test experiment, it can be concluded that the application can show the signal strength based dBm. Thus, this new application is cost-effective as well as user friendly and which can help both the installer and homeowner to find the best position for installing The Void Technology with optimum signal strength.
