By 2021, cloud dashboards were everywhere. Yet PLX-DAQ 2.11 filled a gap others missed:
Students love it because they already know Excel. Researchers use it for quick sanity checks before moving to Python. Industrial techs keep a laptop with PLX-DAQ in their toolkit for debugging PLCs and sensors.
This report details the status of Parallax Data Acquisition tool (PLX-DAQ) Version 2.11. Originally developed by Parallax Inc. for the BOE-Bot robot kit, this software creates a direct bridge between microcontrollers (like the Arduino or Parallax BASIC Stamp) and Microsoft Excel. Version 2.11 is a significant community-driven update released in 2021 designed to fix compatibility issues with modern versions of Excel and Windows 10/11. Plx-daq Version 2.11 Download -2021-
Current Status: The official Parallax website often hosts the legacy Version 2.0. Version 2.11 is primarily hosted on community forums (specifically the Parallax Forums and GitHub repositories) as it is an open-source modification maintained by the community.
The 2021 update wasn’t from Parallax Inc. (the original creator), but from an open‑source maintainer known as “Netman” on the Arduino forums. He quietly released v2.11 as a ZIP file with: By 2021, cloud dashboards were everywhere
That’s the beauty of it: one file, one purpose.
Upload a simple sketch to your Arduino (see example below). Then click "Connect" in PLX-DAQ. Students love it because they already know Excel
The 2021 update (v2.11) is preferred over the original v1.0 for the following reasons:
PLX-DAQ (Parallax Data Acquisition) is an Add-In for Microsoft Excel. It allows real-time data streaming from a microcontroller directly into Excel cells. It eliminates the need for exporting CSV files or copying data from serial monitors manually.
Key Capabilities:
To test if the software is working, upload this simple sketch to your Arduino:
void setup()
// Start serial communication
// Ensure the baud rate in PLX-DAQ matches this number (9600 or 115200)
Serial.begin(9600);
// Print the column headers (Row 1 in Excel)
Serial.println("CLEARDATA");
Serial.println("LABEL,Time,Timer,RandomValue");
void loop()
// Print data to Excel
// Format: ROW,SET,DATA,DATA...
Serial.print("DATA,TIME,TIMER,");
Serial.println(random(0, 100)); // Send a random number
delay(1000); // Update every 1 second
