Sensor Patch: Subgroup: Microcontroller and Communication

This research investigates the feasibility of a sensor patch for newborns. A sensor patch would be a device that is applied to the skin of the newborn. It can monitor the patient's temperature, heart rate, respiration rate, oxygen saturation and asses its general appearance of the skin so that it can check the newborn for jaundice. It should...

Een draadloze sensor voor het monitoren van bederfelijke producten: Draadloze communicatie ontwerp

In deze bachelorthesis wordt een ontwerp gepresenteerd van draadloze communicatie voor een draadloos sensorsysteem voor het automatisch meten van pH en temperatuur. Het is gelukt een volledig passieve RFID tag te selecteren en deze te integreren in een PCB ontwerp met de andere onderdelen van het sensorsysteem. Op basis van een proof of concept...

Wireless Indoor Climate Sensor: Implementing the Control Unit at Ultra Low Power

With the completion of the MIST1431 multi sensor IC a demonstrator developed by the Electronic Instrumentation Laboratory of Delft University of Technology and NXP, a demonstrator that shows the capabilities of the MIST chip was needed. This thesis describes the implementation of the control unit, which has to control the MIST chip and wireless...

Wireless Indoor Climate Sensor: Wireless Communication at Ultra Low Power

The required product is a wireless indoor climate sensor. It is an autonomous sensor that transmits several parameters concerning its environment wirelessly. The product will be used to demonstrate a number of energy efficient sensors. The electronic instrumentation department at Delft University of Technology developed these sensors in...

Run-time Reconfiguration in Wireless Sensor Networks

A wireless sensor network (WSN) consists of multiple small and simple computers (nodes), whose performance is tightly linked to its unpredictable deployment environment. It is nearly impossible to design a WSN that performs well in every scenario; instead they are developed for a specific context, with performance rapidly decreasing when...

Indoor Localization for Wireless Sensor Networks; Applying multiple frequencies to mitigate multipath effects

Localization has an import role in wireless sensor networks, as it adds context to gathered data. The goal of this thesis is to create an application that determines the location of a mobile sensor node in an indoor environment. A secondary goal is to get practical experience with indoor localization. Previously, in a literature review, we...

Radio Wave Propagation in Metal Train Compartments

Wireless sensor networks are being deployed extensively to collect sensory data in various environments under different conditions. A wireless sensor network consists of multiple nodes, each with the ability to communicate using radio waves. The characteristics of the radio link between nodes are largely influenced by their environment. For...
