Abstract [en]

Sensors are light-weight, low powered devices that measure some aspect of a physical or virtual environment and transmit this information in some format. This thesis describes how to integrate a sensor onto devices to enable network connectivity.

The phrase “internet of things” suggests that within a few years many devices will be connected to an internet. Devices, including common household appliances, will transmit and receive data over a network. The CEO of Ericsson has stated that there will be more than 50 billion connected devices by 2020[1]. These devices could be microwaves, fridges, lights, or temperature sensors. Devices that are usually not associated with internet connectivity will be integrated into networks and play a larger role in providing information and controlling other devices. Sensors will have a major role in “the internet of things”. These small computers could be integrated in any appliances and transmit data over the network. The sensors’ low power and low cost, as well as their light weight, makes them very attractive to integrate them into many devices. The goal of this thesis project is to build upon this trend toward “The internet of things” by integrating a sensor into a bathroom scale thus enabling the scale to have networking connectivity. The sensor will be low cost and simple. It should wirelessly or via USB transmit the current weight that it measures to a receiver (specifically a gateway). This gateway will forward the message over the network to a website or mobile phone for visual presentation of the data. This thesis describes different techniques and approaches toward developing this sensor. The thesis also evaluates these different choices in order to select one technique that will be implemented. This solution will be evaluated in terms of its cost and ease of integration into an existing commercially produced scale.

Abstract [sv]

Sensorer är små, energieffektiva apparater som upptäcker variationer i förhållande till någon stimulans och skickar informationen i ett godtyckligt format. Den här uppsatsen beskriver hur man kan integrera en sensor med en apparat för att möjliggöra nätverksuppkoppling.

Uttrycket ”The Internet of things”, översatt på svenska som ”Internet av saker”, konstaterar att inom några år så kommer den mesta av vardaglig elektronik vara uppkopplad mot Internet. Hemelektroniken kommer att skicka och ta emot data över ett nätverk. Ericsson tror att det kommer att vara över 50 miljarder uppkopplade apparater år 2020[1]. Sådana apparater kan vara mikrovågsugnar, frysar, lampor eller termometrar. Apparater som vanligtvis inte förväntas vara uppkopplade mot ett nätverk kommer att bli uppkopplade för att tillföra eller kontrollera information och andra apparater. Sensorer har en viktig roll i denna utveckling. De är små datorer som kan kopplas upp mot flertalet elektroniska apparater och förse dem med en nätverksuppkoppling för att skicka betydelsefull data över ett nätverk. Energieffektiviteten och de låga kostnaderna, så väl som deras små storlekar, gör dem dessutom väldigt attraktiva. Målet med den här uppsatsen är att påbygga ”The Internet of things” genom att tillförse en personvåg med en sensor för att möjliggöra nätverksuppkoppling. Sensor ska vara enkel och billig. Den kommer att trådlöst eller via USB skicka vikter till en mottagare som sedan skickar vidare informationen över nätverket till en hemsida eller mobiltelefon för en grafisk presentation av informationen. Den här rapporten beskriver dem olika teknikerna och approachen mot utvecklingen av sensorn.
