Digilent is now a proud distributor of 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.

The MCC 134 Thermocouple Measurement DAQ HAT features four thermocouple inputs for adding temperature measurement capability to Raspberry Pi-based data acquisition systems. It features 24-bit resolution and provides professional-grade accuracy which is best in class. The MCC 134 also offers open thermocouple detection so users can monitor for broken or disconnected thermocouples and each channel type is selectable on a per-channel basis. Up to eight MCC HATs can be stacked onto one Raspberry Pi.

All DAQ HATs include C/C++® and Python examples and open-source library. Comprehensive API and hardware documentation are also provided.

There are five devices in the MCC DAQ HAT Series. Models are available with voltage inputs, thermocouple inputs, IEPE-based sensor inputs, analog outputs, and digital I/O allowing users to configure multifunction, Raspberry Pi-based data logger solutions.

Raspberry Pi is not included with the MCC 134.

The open-source MCC DAQ HAT Library of commands in C/C++ and Python allows users to develop applications on the Raspberry Pi using the Raspbian®/Raspberry Pi OS®. The library is available to download from GitHub. Comprehensive API and hardware documentation are available. The MCC DAQ HAT Library supports operation with multiple MCC DAQ HATs running concurrently. The library includes example programs developed in C/C++ and Python that users can run to become familiar with the DAQ HAT library and boards; source code is included.

    Excellent Value - Great for Industrial Controls Testing

    Posted by Mark on 17th May 2022

    High quality product, used on an R&D project to design a process oven. Stacked 6 of these boards together to read 24 thermocouples. Easy setup, great value at the price point. Other systems to read the sensors were 2-3x times the cost.

    Great HAT for my application

    Posted by MeasurementGuru on 13th Sep 2020

    I've been searching for an open source thermocouple measurement system to replace a LabVIEW based system. This Raspberry pi HAT met my requirements perfectly. The software install was straightforward and I was up and running within an hour of fedex dropping off the HAT. Everything was provided in the package to install and secure the HAT to my Pi. One recommendation I would make is to design a case for the Pi with one HAT. This would have helped. Fortunately I was able to dig a case out that worked.

    This Pi Hat is awesome.

    I've actually installed the hat and tested it out. I actually really like that it supports different types of thermocouples. I've found the provided software and examples really easy to use. Would honestly recommend it.

    This product has feature of easy useand quick integration of SW controller

    Posted by Dana on 24th Sep 2019

    This product greatly supports my work on automatic controller on/off of 3xshutters and just need 2- hour dll development, and very reliably controlled HW over 3 years without down time.

    Works and easy to use

    Posted by eplotner on 24th Sep 2019

    We needed a way to monitor the temperature of our wash tanks and this did exactly what we needed, actually it was the rinse side but it worked for that also. We can now log temperature so we can see if there is a relationship between a problem we have been having and water temperature.

    It simply did the job.

    Posted by Greg on 3rd Sep 2019

    I bought this for a hobby project, since I had no idea how to calibrate a thermocouple or any kind of thermal probe. This simply solved the problem, and I could move on to the problems I was really trying to solve.
