I'm running a roadtest on a data acquisition HAT (i.e., shield or expansion board) that is used with the Raspberry Pi. It comes with the HAT, a Pi, cables and a high-end accelerometer for vibration testing.
I thought it was a cool device when the sponsor showed it to me. It is a rather inexpensive way to do data logging. Here's the roadtest page for the current running roadtest: Sound and Vibration Measurement HAT for the Raspberry Pi.
I am providing just the accelerometer for this roadtest. But you could hook up a microphone, as well.
This is what the roadtester gets:
Past Pi Data Logging Roadtests...
We have in the past run roadtests using the Raspberry Pi in a data logging application. Those were done with a company called Pico Technology. Here's a link to that roadtest
This system is a bit more expensive and uses thermocouples instead of an high-end accelerometer.
What's Unique About the Sound and Vibration Measurement HAT for the Raspberry Pi.
Good question. Well, it uses a high-end IEPE (integrated electronics piezo-electric) sensor. It features a 24-bit A/D per channel and a maximum sample rate of 51.2 kS/s/ch. Up to eight MCC HATs can be stacked onto one Raspberry Pi. All DAQ HATs include C/C++® and PythonTm examples and open-source library. Comprehensive API and hardware documentation are also provided.
This product is being put out by Digilent through a company called Measurement Computing Corporation (MCC) DAQ and data logging products. MCC is a leading supplier of data acquisition solutions that are easy-to-use, easy-to-integrate, and easy-to-support. for more info go here
I'd encourage you to apply for the Sound and Vibration Measurement HAT for the Raspberry Pi ROADTEST
I know a lot what is going on here on element14. But this one is an interesting one and I didn't want anyone who seeks to learn more about data logging to miss it.
You can apply here. Just click the orange ENROLL NOW button.
Thanks.
