As of 2021, the official source for PLX-DAQ was the Parallax Object Exchange Forum and GitHub mirror repositories. The original Parallax link ( obex.parallax.com ) now redirects to archives. Here is how to safely obtain v2.11:
The 2021 surge in PLX-DAQ 2.11 downloads was largely driven by its utility in remote learning and low-cost research. Students could set up a physics experiment at home, connect an Arduino to their laptop, and instantly generate professional-grade reports in Excel. Its "no-cost" barrier to entry makes it an essential tool for those who do not have access to expensive proprietary software like LabVIEW. Conclusion Plx-daq Version 2.11 Download -2021-
But for its intended job — slow sensors (temperature, humidity, pressure, light, analog voltages) over hours or days — it’s nearly perfect. As of 2021, the official source for PLX-DAQ
Most engineers and makers face a familiar ritual: Students could set up a physics experiment at
Fix: Ensure you are separating your values strictly with commas ( , ) in your code, and verify that your system regional settings use commas (and not semicolons) as list separators.
