Raspberry Pi® HAT expansion module for IEPE sensors

MCC 172 is a 2-channel DAQ HAT for sound and vibration measurements with IEPE sensors such as accelerometers and microphones. The fourth module in the series provides two simultaneously acquired analog inputs with 24-bit resolution and sampling rates up to 51.2 kS/s per channel. Piezoelectric sensors according to the IEPE standard can be connected directly, no additional signal conditioning is required. The module captures aliasing-free dynamic signals up to 23 kHz. To increase the number of channels, up to eight DAQ HATs (Hardware Attached on Top) can be plugged directly into the GPIO interface of the Raspberry Pi and synchronized up to a total sampling rate of 307.2 kS/s.

MCC offers a number of other DAQ HATs that equip the Raspberry Pi with analog and digital I/Os and turn it into an individual multifunctional solution.

The DAQ HAT series is specially designed for test and measurement tasks and professional OEM/ODM use. The DAQ HATs include a high-quality software library that supports Python and C/C++ and enables fast and easy development on Linux. The open source library, developed and maintained by MCC itself, comes with complete documentation and extensive examples. Like all MCC products, DAQ HATs undergo extensive device validation. The validation process also includes the sample programs and installation on the most popular Linux distributions.
