USB serial data logger software
Record serial test data without building your own logger.
DaqSense is a local-first desktop serial data logger for prototype and test benches. It turns supported serial rows into live tables and useful files while preserving the original input.
What changes with DaqSense
The goal is a dependable test record, not another software project to maintain.
Capture
Select a serial device and baud rate, then preserve incoming lines in a raw local record.
Understand
Apply parser rules, field names, formulas, units, live tables, charts, and diagnostics.
Use the result
Write parsed CSV files and export recorded sessions to spreadsheet files for analysis and sharing.
Common signs the current workflow is costing time
- A terminal shows the stream but does not create the test record the team needs.
- A quick logging script grows into an undocumented application.
- Post-run cleanup repeats the same parsing and formula work every time.
- Malformed lines make structured output unreliable or difficult to audit.
- Only one person knows how the current capture workflow fits together.
A simpler workflow
- 1
Connect
Choose the serial device, baud rate, and saved profile for the setup.
- 2
Parse
Split supported messages into named datasets and fields while retaining unmatched input in the raw log.
- 3
Calculate and watch
Add formula columns, units, live tables, charts, and diagnostics for the active stream.
- 4
Record and export
Save raw and parsed files locally, then export the recorded session for spreadsheet analysis.
Example workflow
USB-serial prototype run
Input
An ESP32 prints time, temperature, pressure, and status messages during a supervised experiment.
In DaqSense
DaqSense separates supported measurements into columns, shows live values, calculates a derived field, and records parser warnings.
Output
The engineer receives the untouched raw stream, clean parsed CSV data, and a spreadsheet export from the same session.
A good fit when
- ✓ The device appears as a supported serial port on Windows, macOS, or Linux.
- ✓ The stream contains line-oriented text that the current parser supports.
- ✓ The test needs a local raw record and analysis-ready structured files.
- ✓ A visible, reusable workflow is more useful than another custom script.
Use another approach when
- — The job requires Modbus, CAN, OPC UA, several synchronized devices, or other unsupported connections.
- — The station needs a programmable sequence, instrument control, or automated pass/fail logic.
- — A basic terminal or ten-line script already solves the complete one-off task.
