  1. 1. Application development for collecting and visualizing data from a portable sensor

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Oscar Kellner; Kasper Silverforsen; [2017]
    Nyckelord :application; sensor; mobile; portable; pollution; greeniot;

    Sammanfattning : Our task was to produce a mobile application that could retrieve and visualize emission data from portable measurement sensors. The purpose of this project is to develop an user interface for the portable sensors since it has not been done before. The project is an opensource project. LÄS MER

  3. 2. Energy harvesting power supply for wireless sensor networks : Investigation of piezo- and thermoelectric micro generators

    Kandidat-uppsats, Institutionen för teknikvetenskaper

    Författare :Nils Edvinsson; [2013]
    Nyckelord :energy harvesting piezo wireless sensor networks duty cycling UPWIS Seebeck Peltier piezoelectric thermoelectric;

    Sammanfattning : Computers and their constituent electronics continue to shrink. The same amount of work can be done with increasingly smaller and cheaper components that need less power to function than before. In wireless sensor networks, the energy needed by one sensor node borders the amount that is already present in its immediate surroundings. LÄS MER
