   Sammanfattning : The use of Internet of Things systems has increased to meet the need for smart systems in various fields, such as smart homes, intelligent industries, medical systems, agriculture, and the military. IoT networks are expanding daily to include hundreds and thousands of IoT devices, which transmit information through other linked devices to reach the network sink or gateway. LÄS MER

3. 2. Fire detector sensor nodes using Long Range (LoRa) radio communication : Branddetektorsensorer som använder Long Range (LoRa)

   M1-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Roney Yelda; [2023]
   Nyckelord :;

   Sammanfattning : Fire can be fatal, burning homes and forests and its emissions can pollute the air. To prevent these types of catastrophes, it will be necessary to develop a sensor module capable of detecting and alerting humans by sending a signal via a network called The Things Network (TTN).

   Sammanfattning : AstraZeneca är ett medicinskt företag lokaliserat i Södertälje som har cirka 900 luftfilterboxar hos sin anläggning i Gärtuna. Dessa filterboxar kan vara opraktiska att hålla koll på eftersom de är utspridda uppe på vindarna, samt att det behövs bra framförhållning vid filterbyten eftersom vissa filter innehåller farliga ämnen.

5. 4. Trådlös sensornod för mätningar av växthusgaser

   M1-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Johnny Yelda; Lucas Eriksson; [2022]
   Nyckelord :LoRa; TTN; MKR1310; Gateway;

   Sammanfattning : Greenhouse gas emissions are the biggest challenge that humans are facing because of how they can affect the global warming and the negative impact on earth. To be able to control Greenhouse gas emissions or even to minimize them we first need to be able to monitor them and then find solutions to minimize them. LÄS MER

7. 5. Implementation and performance analysis of multiple concurrent WPAN protocols on a system-on-chip

   Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

   Författare :Juni Hag; [2022]
   Nyckelord :Bluetooth; Bluetooth Low Energy; BLE; Zigbee; 802.15.4; IEEE 802.15.4; WPAN; wireless protocols; sensor networks; IoT; Internet of Things; multiprotocol; TDMA; SoC;

   Sammanfattning : The development of new energy efficient Wireless Personal Area Network (WPAN) protocols is a big factor for the increased interest in Internet of Things (IoT). However, the many protocols with overlapping applications have led to competing standards and sensor networks using different protocols, even to perform the same tasks. LÄS MER
