Do-It-Yourself (DIY) Wireless Vibration Measurement System
The ease of interfacing with Digiducer’s Digital USB Accelerometer (333D01) enables some amazing test possibilities.
The sensor benefits from the ubiquitous USB Audio protocol making it easy to interface with inexpensive single board computers like the Raspberry Pi and BeagleBone Black. Adding a Wi-Fi dongle and external USB power pack to the small computers is straightforward. You can create your very own stand-alone wireless vibration acquisition system using the Model 333D01 Digiducer.
Data acquisition is as easy as using a remote desktop program like Virtual Network Computing (VNC) to connect to Audacity software that captures vibration data and saves it in a selected file format. The data can be transferred from the acquisition computer using something as simple as FTP. A drive on the local PC can be mapped for network access.
Free software development environments enable the development of custom applications. These applications can be as simple as periodically waking up to record a block of vibration data. More elaborate applications calculate an RMS overall vibration and output the data using a standard industrial network protocol such a Modbus TCP/IP. The possibilities are endless.
This DIY solution is all possible with a Digiducer and less than $100 of additional equipment. Wireless vibration measurements, simplified.
