Final thoughts  As the competition comes to a close, these are my final thoughts... I feel this sensor is well-suited for many applications such as industrial IoT and field devices. Because of its high sensitivity, I am able to sense the vibrations easily from my hard disk experiment. Although at a hobbyist level, it may be a hard decision due to the high price. In my experiments, I have only done FFT analysis. But the possibilities are endless and it is up to the user's imagination to inte ...
Experiment 4 (FFT Dashboard with Mbed DSP)  Please read my other blog posts too if you haven't Experimenting with Vibration Sensors - zst123's Blog Posts   Introduction  Since I still have time for one last experiment before the deadline, I decided to try out a live FFT plot using the Digital Signal Processing (DSP) functionality on this powerful microcontroller. I actually saw from the other challengers on how they use ARM DSP inside STM32Cube for FFT. It is very interesting an ...
Experiment 3 (Fourier Transform Analysis to find RPM)  Please read my other blog posts too if you haven't Experimenting with Vibration Sensors - zst123's Blog Posts   Objective  This experiment is aimed for advanced users as it includes the use of Fast Fourier Transform (FFT). Today this will be a very long post as we shall collect many test results from different spinning devices! I will apply FFT to extract the frequencies presented to the vibration sensor.   From the resul ...
Experiment 2 (Detect Spinning Fan Obstructions)  This is a continuation of Experiment 1 Experimenting with Vibration Sensors - Characterize RPM of Spinning Devices #3 (Initial Setup & Tapping Experiment)   Please read my other blog posts too if you haven't Experimenting with Vibration Sensors - zst123's Blog Posts   Objective  This experiment is of intermediate difficulty. Previously I faced speed limitations when using the Arduino Graph Plotter and today I will crea ...
Experiment 1 (Initial Setup & Tapping Experiment)  ObjectiveThis experiment is suitable for beginners. I will walk through how to set up the vibration sensor to:   1. Turn on a red LED when vibration is detected 2. Plot a graph on a PC to observe the vibrations   Microcontroller SetupTo make it simple for beginners, I will be coding using Mbed which is a framework for ARM microcontrollers and very similar to the Arduino environment. The Mbed has an online compiler through the ...
  Introduction & Unboxing   The Kit I have just received the Vibration Sensor Kit in the mail! Just in time this weekend for me to experiment my first tests!   In the box, we have the vibration sensor itself (VS-BV203-B) bundled with a Nucleo Board (NUCLEO-H743ZI) and a Bluetooth Expansion Board (X-NUCLEO-IDB05A1).   Let’s go through each item together!   Thank you to the sponsor KEMET for this experiment. (I was confused at first due to the labelling but ...
Introduction   Hello everyone, thank you to the organisers for giving me the opportunity for this experiment.   A short introduction of myself. I have finished a diploma in Electrical Engineering and I am waiting to further my studies in a university in a few months' time. I love to play with Electronics from a hobby level too.   Experiments Planned   I aim to break up my blog post into a few parts.   Firstly I will aim at a beginner's level because I feel there's not a ...
