Experimenting with vibration sensors – Machinery safety Blog #11 (Review & Final Thoughts)   For those of you that have read my blogs, you might have a good idea how my review and final thoughts will be.   Review:   From the day I received the KEMET Vibration Sensor I had a good idea that this challenge will be fun. My proposal was to use the sensor to check machinery vibrations and shut it down when the vibrations were too much. I was originally going to use the Nucl ...
Happy New Year everyone,   I have been so intrigued with the KEMET Vibration Sensor I can’t stop experimenting.   On the weekend, I was trying different uses for the KEMET Vibration Sensor. Making sure I wasn’t interfering with anyone’s challenge idea, I decided to attach the sensor to my throat where my voice box would be located. Amazingly when I said the alphabet there was a distinct difference between each letter. If each letter is added with it's specific vibr ...
Hello Element14 community,   Sorry for so many blog updates on my challenge. I know we only need to do 2, but I'm so into it that I want to share the experience.   To follow-up on yesterdays blog, I am posting photos of the process:   Start-up:   Choose which program A - Machinery Safety or B - Test Sensor     If "A" is chosen: (Set-up with push buttons)      Starts the "Machinery Safety program".      - First y ...
Hello community,   So, I'm finished the code to run the KEMET vibration sensor. I did attach it below. I have also attached 2 videos of everything working.   The experiment review: My proposal was to use the KEMET Vibration Sensor as a machine safety device. The sensor would get the average vibration of the machine, the user would enter the shutdown limit and if this limit is reached, the machine would shut down. With machines that I use at work, unbalanced machines can be deadly. ...
This is a 2 part update,   First, the experimenting with the sensor controlling the machine to shut off will be done in a smaller version. I will hook it up to my CNC at home. I will check the different vibrations from the big machines (but we are using 660v at work) so no electrical work for me. My CNC at home will work great for the shutdown tests.   Second, I had an idea this morning for another use, medical. I taped the sensor to my wrist where my pulse is, it picked up the vibra ...
Machine safety Blog #6   I am doing this update because I went out of my comfort zone with programming. Years ago this wouldn't have been such a big deal for myself and I'm sure lots of you reading this could do it in your sleep. For me, I'm kind of proud of what I did.   So my issue was I wanted to test the sensor on other things besides machinery. Just a simple program to read the sensor. So I was loading the Arduino with the simple code then reloading it with the machinery safety ...
Vibration Sensor Demo   Below is Arduino code for testing the KEMET vibration sensors sensitivity. I also attached a video of the code running with the sensor attached to a small fan. In the video you can see when I run the fan it picks up the slight vibration (I couldn't even feel). I have an LCD display attached to show the readouts.   Below is the code for vibration sensor test reading:   #include <LiquidCrystal.h> const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 ...
Hi Everyone,   This is an update on my progress with "Experimenting with Vibration Sensors - Machine Safety". I have programmed the board (Arduino Mega 2560) and ready for testing. I decided to go with the Arduino as I am more familiar with everything about it. I have it start with a calibration of the sensor by doing a loop 15 times over 15 seconds. Each loop it reads the sensor and saves the total, after it divides the total by 15 for the average. I will post my code next blog. I brought ...
Experimenting with Vibration Sensors - Machinery Safety (Info)   This is just an information blog. For those of you who feel more comfortable with programming the Arduino, here is some information on how to use the Nucleo-H743 with the Arduino IDE:   Open the Arduino IDE File > Preferences Enter this URL in the "Additional Boards Manager URLs" : https://github.com/stm32duino/BoardManagerFiles/raw/master/STM32/package_stm_index.json Click on the icon at the end of the box. Clic ...
Experimenting with Vibration Sensors – Machinery Safety Blog #2   I received the kit yesterday and I have to say, I am impressed. The Kemet Vibration Sensor has a very long cord which will make it easier to set up the experiments. The sensor itself is tiny (as you can see in the photos below). It is amazing what can be put into such a tiny casing. I will most likely be using the Nucleo-144 development board with the sensor. I’m looking forward to starting the testing and seein ...
Experimenting with Vibration Sensors   Machinery Safety     About myself: I am a cabinetmaker for the past 33 years and my hobby is electronics. I have been in charge of machinery maintenance and first aid for many years. Dealing with the electronics and safety of the machines daily, trying to improve the safe operation whenever I can. Some of the injuries that happen can be avoided with warning sensors. Being in the trade for so many years I have seen the worst, experiencing i ...
