    Nyckelord :;

    Sammanfattning : This master's thesis, conducted in collaboration with Knowit Connectivity, aims to develop a booking device for meeting rooms. The focus of the project is to identify and mitigate disturbances in the C-PIR sensor introduced by Haili Liu et al. LÄS MER

  4. 3. Smart Bird Feeder : Self-propelled and interactive

    Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Daniel Tegbrant; Edvin Falkman; [2022]
    Nyckelord :PIR sensor; Birds; Mechatronics; Python; Ultrasonic sensor; Feeding mechanism; Twitter; PIR-sensor; Fåglar; Mekatronik; Python; Ultraljudsensor; Matningsordning; Twitter;

    Sammanfattning : Bird feeding is somthing most are familiar with, either when children are feeding the swans or adults using some type of bird feeder in the garden. This project took that as inspiration to create something that automatically feed the birds while also monitoring them by capturing a picture and sending out this information as a teet on Twitter.

  5. 4. Microwave Radar Implementation in Outdoor Home Alarm Systems

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Isabelle Larsson; Gustaf von Plomgren; [2020]
    Nyckelord :radar; microwave radar; home alarm systems; home alarm; alarm; passive infrared; PIR; Technology and Engineering;

    Sammanfattning : The use of short range microwave radars for motion sensing purposes are on the rise in multiple industries, as they are accurate, small in size and relatively cheap. The automotive industry, in particular, has pushed the development forward. Lately, the home alarm industry has also been glancing at the technology. LÄS MER

  7. 5. Komparativ studie av rörelsedetektorer i ett övervakningssystem

    M1-uppsats, Jönköping University/JTH, Datateknik och informatik

    Författare :Makail Ismail Ahmed; Antonio Sürer; [2020]
    Nyckelord :PIR;

    Sammanfattning : False alarms in home surveillance systems are an annoyance for customers and it has become a much-debated topic. There are several previous studies where the purpose is to reduce the number of false alarms in home surveillance systems, but not about combining different types of sensors in different sensitivities that complement each other.
