Dörröppningar till en operationssal under en pågående operation ökar infektionsrisken. På Centraloperation, Karolinska Universitetssjukhuset Solna, öppnas dörrarna till operationssalen fler gånger än nödvändigt. Muntlig information till personalen har inte minskat antalet dörröppningar på lång sikt. En trådlös tekniklösning som räknar och visualiserar antalet dörröppningar tros ha en mer långvarig effekt, därför skulle en prototyp tas fram. En litteraturstudie gjordes för att hitta komponenter och för att med dessa skapa prototypen.   Prototypen kan räkna och visualisera antalet dörröppningar från en dörr. Då en operationssal oftast har tre dörrar är visualiseringen förberedd för att kunna visa antalet för dessa. Prototypen behöver vidareutvecklas för att kunna användas på under en operation. / Door openings to an operating theatre, during an ongoing operation, increases the risk of infection. At the Central operation department, Karolinska University Hospital Solna, the doors open more frequently than necessary. Oral information to the staff has not reduced the number of door openings for a longer time. A wireless solution that counts and visualizes is believed to have a more longlasting effect, therefore a prototype would be created. A literature study was performed in order to find components and with those build the prototype. The prototype is able to count and visualize the number of door openings from one door. However, since many operating theatres have three doors, the visualization is prepared for this. To be able to use this system during an operation the prototype needs to be further developed.

This degree project investigates the possibility to develop and re-design an IoT solution called NOT!FY, offered by the company Omnitor. NOT!FY is used by users who are hard of hearing or deaf as a complement to an accessibility communication application. It functions by registering incoming calls and activating a relay connected to, for example, a light source, notifying the user. The current problems that Omnitor experiences with NOT!FY is its price, production difficulties, size and design. The project will take on these problems by investigating the market of programmable devices and, through comparative analysis, choosing a platform to transfer and improve upon the current NOT!FY functionalities. The devices were decided together with Omnitor and a grant calculation was drafted to evaluate which units yielded the best profit. With the help of the grant calculation, Raspberry Pi Zero W and ESP8266 were the chosen devices. A basic evaluation was performed to verify that the implemented functions of ESP8266 and Raspberry Pi Zero W functioned as intended. An in-depth evaluation and functional verification were performed on the finalized prototype. It confirmed the prototype’s functionality and the possibility to replace the current product in use by Omnitor. / Detta projekt undersöker möjligheten att utveckla och designa om en IoT-lösning kallad NOT!FY, som erbjuds av företaget Omnitor AB. NOT!FY används av döva eller hörselskadade användare som ett komplement till en tillgänglighetsanpassad kommunikationsapplikation. Den fungerar genom att registrera inkommande samtal och aktivera ett relä som är anslutet till exempel en ljuskälla för att meddela användaren. De nuvarande problemen som Omnitor upplever med NOT!FY är dess pris, produktionssvårigheter, storlek och design. Projektet kommer att ta sig an dessa problem genom att undersöka marknaden för programmerbara enheter och genom en jämförande analys välja en plattform att överföra och förbättra funktionerna från den nuvarande produkten. Enheterna bestämdes tillsammans med Omnitor och en bidragskalkyl är framtagen för att utvärdera vilka enheter som gav bäst vinst. Med hjälp av bidragskalkylen var Raspberry Pi Zero W och ESP8266 de valda enheterna. En grundläggande utvärdering utfördes för att verifiera att de implementerade funktionerna i ESP8266 och Raspberry Pi Zero W fungerade som avsett. En mer ingående utvärdering och funktionell verifiering utfördes på den färdiga prototypen. Detta bekräftade prototypens funktionalitet och möjligheten att ersätta den nuvarande produkten som används av Omnitor.

This thesis describes creation of dynamically evolvable node, which will cooperate with other nodes. Group of these nodes will then create a distributed control system. The MQTT protocol is used for communications purposes between individual nodes. As hardware platform is used ESP32 and ESP8266. Whole operating system is written in MicroPython and supports a live uploading of user applications written in the same language. Later in thesis is decribed creation of monitoring node on Raspberry Pi, which control network. Complete system can be then used to control a intelligent house.

This work deals with connecting remote devices measure data of various types from physical quantities such as a temperature, a humidity to data displaying CPU or memory usage of the system to the user. The system uses Blockly to controlling logic and dependencies between devices. In the work is used lots of technologies for examples: MQTT, Websockets, GSM, Lightweight Mesh and others. The system is based on microservice which named is Flask. Flask service is an application interface for HTTP services of Python programming language. This can provide measured data by graphs and predefined components for viewing data. For controlling system was used single-board computer Raspberry Pi with a multitouch 7-inch display.

This thesis discusses the topic of internet of things and its protocols and compatible devices in the field of home automation. Also defines the requirements for the system which designs in the form of concept and afterward makes practical realization.

Excessive droughts on the African continent have caused the Swedish Meteorological and Hydrological Institute to launch a program of gathering data in hopes of producing models for rainfalls and droughts. A sensor capable of gathering such data has already been chosen, however there remains the problem of conveniently retrieving data from each of the sensors spread over a large area of land. To accomplish this goal, a small, cheap and efficient wireless capable module would need to be used. A possible candidate is the new WiFi-module from Espress if designated ESP8266. It is an extremely cheap and versatile wireless SoC that is able to perform the task of a wireless communications adapter for the sensor unit. The point of this thesis is to investigate the suitability of IEEE 802.11 for the task, and produce a piece of firmware for the ESP8266. The firmware shall enable it to be attached to a sensor and operate as a wireless mesh node in a self-organizing WLAN sensor network, enabling data retrieval via WiFi multi-hop deliveries.

This master thesis deals with the greenhouse effect, various gases and methods of measurement. On the greenhouse effect is viewed from its historical dating, despite changes in atmospheric composition. It contains a theoretical analysis of the individual gases. It focuses on the most harmful greenhouse gases such as water vapor, carbon dioxide, nitrous oxide, methane, ozone, chlorofluorocarbons and halons. Analysis methods for detection of gaseous substances. Part of this work is focus on the detection of nitrogen dioxide, chloro-fluorocarbon and methane. The data is processed using a ATmega’s microcontroller and then sent to an Internet server thingspeak.com. If the device proves successful, will be used as a laboratory exercise in the course Ecology in electronics.
