  1. 1. Erlang as an alternative to a non-functional language for communication in a faulttolerant IoT sensor network

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Jimmy Holdö; [2020-02-17]
    Keywords : Internet of Things; Wireless Sensor Network; Erlang; IEEE 802.15.4; ZigBee; Network topology;

    Abstract : This thesis compares a C++ prototype and an Erlang prototype for an Internet ofThings application. Internet of Things applications are difficult to program becausethey consist of a distributed environment of heterogeneous devices, where each devicecan have limited resources and connectivity technologies.

  2. 2. Active Infrared light power supply for indoor wireless sensor nodes

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Jialei Chen; [2020]
    Keywords : Energy Harvesting; IR; WSN; Photovoltaic;

    Abstract : In order to expand the energy source in energy harvesting, this thesis explores the feasibility of using infrared light source as the energy source. Firstly, the thesis investigated the current energy harvesting solution and the way of using infrared light energy, and determined the use of crystalline solar panels as energy harvesters. READ MORE

  3. 3. Detection of motor skidding in autonomous lawn mowers : Detection of skidding in autonomous lawn mower using machine learning technique MLP with wheel motor currents and IMU.

    University essay from Jönköping University/JTH, Datateknik och informatik

    Author : Daniel Truong; [2020]
    Keywords : robot; autonomous; lawn mower; machine learning; detection; skidding;

    Abstract : Purpose – The purpose of the thesis is to evaluate the accuracy of two different approaches of how to detect skidding in autonomous lawn mowers. Using the motor currents and inertia sensors from the mower, a neural network is applied to predict if there was a skidding or not. READ MORE

  4. 4. Presence Detectors and Remote Heartbeat Sensing Using Radar Technology
