I want to a system with multiple piezoelectric sensors and play a sound every time the piezoelectric sensor detects vibrations. Any idea how I can do that on Linux?
I have a 12 ton hydraulic press, and I would like to measure the output.
One way is to hook up an analog gauge to the reservoir, but I was thinking it would be nice to just have a piezoelectric pad under the ram to measure pressure.
Is there such a thing for such high pressures that would work with Arduino?
Does anyone have any experience using a piezoelectric vibration sensor? I'm looking at this one:
https://banggood.app.link/Zc7qoBRMg9
I'm interested to know how sensitive it is and what the data read from it looks like. For example, is it sensitive enough to show the difference between an electrical device operating normally vs one thats come near the end of its life? I'm thinking of something like say a harddrive which would have a "normal" vibration, then a more pronounced vibration as it got close to failure. That's just an example and not the use case I'd apply this to.
Thanks.
I'm looking into making my own electronic drum kit and I need pizeo's. However, I don't want to spend $20 getting them all from the window alarms at the dollar store.
This is the best tl;dr I could make, original reduced by 39%. (I'm a bot)
> Peugeot, along with agency BETC, designed the first billboard composed of thousands of acoustic sensors with piezoelectric properties, capable of charging electric vehicles using cities' noise pollution.
> The device absorbs the vibrations emitted by city sound waves to help recharge the new e-208, 100% electric model.
> To demonstrate their commitment to Unboring the Future, as well as its notable entry into the electrical market, Peugeot highlighted the virtues of a promising new technology: piezo-electricity, which generates an electric current when put under stress-in this case, sound.
> Almost a year after the launch of the Peugeot E-LEGEND concept car, Peugeot 's new 208 is in line with this vision, particularly the electric model.
> With the new Peugeot e-208, the future isn't only exciting, it is also quieter.
> Tiphaine du Plessis, Managing Director of BETC, emphasizes that "This project is perfectly in line with Peugeot's Unboring The Future vision, which also consists of making a stand and addressing many social issues, including noise pollution."

Hello! I'm trying to build a pressure sensor with a piezoelectric and an instrumentation amplifier. However, I am having troubles with the instrumentation amplifier since there are a lot of circuit diagrams and the ones I have built are not giving me the results I want. I only need it to give different voltage levels according to the pressure that is being applied to the piezo. (The more pressure you apply on the piezo, the higher voltage it gives). Also, I'm using TL084 operational amplifiers. Please let me know if you have any diagram I could use. By the way, thank you for reading. I'll be glad to read all your sugerences.
Iβve been reading about piezo sensors and while I do understand that they can act like a generator via pressure Iβm still lost.
If they make very little electricity how are they used in cars and such?
Iβve done my own research but I am hoping someone can dumb it down for me.
Hello,
I'm trying to simulate a preamplifier stage for a piezoelectric diaphragm to use it as sensor. I want to simulate a little this sensor but I m stuck to build a basic approximation model. I don't know how does impedance and capacitance are wired.
I try several schematic but I dont know which one to use
I just have small information from datasheet :
| Resonant frequency | 4 kHz |
|---|---|
| Resonant impedance (max) | 1000 Ohm |
| Capacitance @1kHz | 8 nF |
I just want to approximate a little the sensor (more than just source and 1K resistor) to take capacitance in account especially to simulate noise in LTSpice.
Can you help me to choose ?
So, I have a crazy idea. You know those "telephones" made of tin cans and a bit of string? I'm trying to bring that into the 21st century.
The idea is that when you speak into a can, the bottom of the can works as a diaphragm and vibrates. The vibration travels along the string and into the other can, causing its bottom to vibrate in the same way which creates sound. I'm going to put a piezoelectric vibration sensor in the receiver can, and connect that to an Arduino which will then send the vibration data over the Internet. It will be received by another Arduino, somewhere else in the world. This Arduino is connected to some component that's inside the "sender" can of a can phone, which vibrates the bottom of that can. The vibration travels along the string to the receiver can, and finally it can be heard as sound by the recipient.
Now, I'm reasonably certain this should work, but I'm not sure what I could use to reproduce the vibration on the other side. Would a speaker do it, or is there some kind of special component I could use?
Also, if my idea is really fucking stupid, please tell me so I don't waste time and money on it...
New to component development (traditionally web/software developer) here, looking to build a custom percussive midi pad device, and saw a tutorial mentioning these. (https://www.instructables.com/id/Homemade-Electronic-Drum-Kit/) I see very little info on "Piezoelectric pressure sensors" on the web aside from a wiki. Can anyone recommend a model and/or source for some I could use with arduino/teensy to build my project?
Hey AskElectronics, I'm trying to design a circuit powered off a 9V battery to turn on 2 half meter long led strips when a drum is hit.
The plan is to stick a piezo sensor(like this: http://letsmakerobots.com/files/field_primary_image/piezotransducer.jpg) onto the drum somewhere) and connect it to a circuit that will make the led strips light up when the drum is hit.
I've tried using this circuit: http://interface.khm.de/wp-content/uploads/2011/12/PiezoPreamp_bread_V2_sch.png but am getting no joy.
When the piezo sensor that i have is not connected to anything, it registers a maximum of about 40mV when the table is tapped.
Currently, I'm dropping the 9v to 5V and I've tried using an lm311 but the output sits at 4v and I don't know why.
I've also tried an lm741 but am getting very little joy - I think because of the low input voltage from the sensor.
I've also tried this: http://www.engineersgarage.com/electronic-circuits/piezo-sensor-input but zero output. I had to substitute the bc548 for bc547
I'm not sure at all how I'm supposed to continue this. Nothing seems to work. Please help
