Digiducer Vibration SensorΒΆ

../../_images/digiducer.jpg

The foglamp-south-digiducer plugin allows a Digiducer 333D01 USB Digital Accelerometer to be attached to FogLAMP for the collection of vibration data. The Digiducer is a piezoelectric accelerometer housed in a rugged enclosure complete with a data conditioning and acquisition interface that only requires a USB port on the FogLAMP device for connectivity.

The plugin allows for two modes of operation; continuous reading of the vibration data or sampled reading of the vibration data. In sampled mode the user configures a sample period and interval. The plugin will then read data for the sample period and forward it to the FogLAMP storage service. It will then pause collection for the sample interval before again collecting data. This repeats indefinitely.
