    Keywords : Radio Frequency energy harvesting; Antenna as a sensor; Long-Term Evolution; Rectifier; Printed Circuit Board; Altium Designer; Matching network; Voltage multiplier; Schottky diodes; Multiband LTE antenna; Ambient energy harvesting; Low power Internet of Things; Wireless power transfer; Radiofrekvensenergiskörd; Antenn som sensor; LTE; Likriktare; Printed Circuit Board; Altium Designer; Matchande nätverk; Spänningsmultiplikator; Schottky-dioder; Multiband LTE-antenn; Omgivande energiskörd; Lågeffekt Internet of Things; Trådlös kraftöverföring;

    Abstract : This thesis primarily deals with the concept of designing an antenna based device to harvest energy from Radio Frequency (RF) and using the harvested energy to sense the available Long Term Evolution (LTE) network in order for the Internet of Things (IoT) devices to connect to the network for the purpose of transmitting and receiving data. Secondarily the importance of this project is targeting how to conserve battery power in an IoT device and extend it’s lifetime. READ MORE

  4. 18. Lighting Energy Savings in an Office Environment Simulating a Motion Detection Dimming System

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Ida Gutenwik; Nanitza Gonzales Allendes; [2022]
    Keywords : Motion Detection Dimming; Wireless Sensor Network; Energy Consumption; Daylight-Linked Control System; Rörelsedetekterande Dimmers; Trådlöst Sensornätverk; Energikonsumption; Dagsljus-Kopplade Kontrollsystem;

    Abstract : Shortages of electricity in larger cities in Sweden are becoming more common and might increase with an increased consumption. The thesis focuses on lights due to approximately 19 - 20% of the total electricity consumption coming from lights. READ MORE

  5. 19. Current measurements of low-power battery driven devices

    University essay from Uppsala universitet/Signaler och system

    Author : Marcus Wahlberg; [2022]
    Keywords : Current meter; current measurement; shunt resistor; auto-range; current-range;

    Abstract : A current meter has been designed, intended for surveillance of low-power battery driven devices with a large dynamic range in their current consumption. Among such devices may, for example, be nodes in a wireless sensor network (WSN). READ MORE

  6. 20. Implementation and performance analysis of multiple concurrent WPAN protocols on a system-on-chip

    University essay from Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Author : Juni Hag; [2022]
    Keywords : 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;

    Abstract : 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. READ MORE
