Simulating the Energy Transition: Raspberry Pi Hardware Hub

Before the project was started, there was an energy system integrator demonstrator. This demonstrator was purely software, there was no physical interaction possible with it. It demonstrated the energy system by simulations. The objective of this project was to design and built peripherals that represents the components of an energy system....

Low-Power Gesture Recognition Using Convolutional Neural Networks and Ambient Lighting

This paper presents a study focused on developing an efficient signal processing pipeline and identifying suitable machine learning models for real-time gesture recognition using a testbed consisting of an Arduino Nano 33 BLE and three OPT101 photodiodes. Our research aims to address the challenges of limited computational power whilst...

Recognising Gestures Using Ambient Light and Convolutional Neural Networks: Adapting Convolutional Neural Networks for Gesture Recognition on Resource-constrained Microcontrollers

This paper presents how a convolutional neural network can be constructed in order to recognise gestures using photodiodes and ambient light. A number of candidates are presented and evaluated, with the most performant being adopted for in-depth analysis. This network is then compressed in order to be ran on an Arduino Nano 33 BLE...

Hand Gesture Recognition on Arduino Using Recurrent Neural Networks and Ambient Light

Touching physical buttons to interact with public electronic devices has raised some concerns regrading disease transmission following the COVID-19 pandemic. The use of hand gestures as a touchless replacement sounds appealing, but comes with the challenge of recognizing which gesture is being performed by the user, with only the processing...

Solar Powered Weather Station: Sensors and Control

Increasing concerns surrounding the influence of urban climate on the livability of cities and the health of citizens lead to a need for environmental data on a more localized scale. Self-powered weather stations that use the many WiFi networks spanning the city to transmit their data are a promising solution to increase the amount of data on...

Autonomous Temperature Sensor for Smart Agriculture: Smart Measurement and Control

Fruit-frost during spring is one of the main causes of damage to the harvest of fruit in orchards. Various systems using different methods of preventing spring-frost are available on the market. To determine when these systems should be activated, the temperature in the orchard needs to be determined. In this project, a self-sustaining...

Microinjector: An OpenLabware Project

OpenLabware is an ongoing trend to create easy to use, robust, and open source lab equipment at a fraction of the cost of commercial alternatives. One such a project is known as the OpenSpritzer designed by Forman et al. [8]. The OpenSpritzer claims to be a direct replacement of a pressure injection system (Picospritzer) that can be used to...

Smart sensors and communication using Internet of Things in Supermarkets: Obstruction detection

Internet of things (IoT) applications become more and more prominent in our modern society. IoT has the potential to improve business processes and change the ways we live. KPN New Business has a high affinity with IoT projects and supplied the problem definition that this project builds on. The project has been done in close collaboration with...
