A PC-based pulse oximeter is a USB-connected SpO2 sensor that plugs directly into a computer to display real-time blood oxygen saturation (SpO2), pulse rate (PR), and pulse waveform on a Windows PC no standalone display screen required. The ST-T130-01 is a reusable adult finger clip sensor built for this exact purpose: continuous or spot-check monitoring streamed live to free companion software.
This USB pulse oximeter sensor is designed for clinics, home health monitoring, sleep labs, fitness testing, and research settings that need to log and review oxygen saturation data directly on a computer instead of a small handheld screen.
Key Benefits
- Live PC monitoring real-time SpO2 and pulse rate readings displayed directly on your Windows computer screen
- Multi-patient tracking the included software displays up to 4 persons’ parameters simultaneously
- Data logging built in automatically saves up to 2 hours of session data, exportable to an Excel-readable file for easy review and reporting
- Trend and waveform view visualise pulse waveform and SpO2/PR trends over time, not just a single snapshot reading
- Multi-language software available in English, Chinese, German, French, Italian, Dutch, Russian, and Spanish
- Comfortable, reusable design soft-touch TPU finger clip suitable for adult use, easy to clean and disinfect between uses
How the PC-Based SpO2 Sensor Works
- Connect the ST-T130-01 finger clip sensor to your computer’s USB port (install the CH340 USB-to-serial driver first if it isn’t already installed).
- Open the included SpO2.exe program to start real-time monitoring.
- Clip the sensor onto an adult finger SpO2, pulse rate, and waveform appear instantly in the display window.
- Use the review program to reopen saved sessions, generate printed reports, or export readings to Excel.
- Disconnect the sensor to end the session; you’ll be prompted to save the recorded data.

Frequently Asked Questions
Does the ST-T130-01 pulse oximeter need special software?Â
Yes. It comes with a free Windows PC application (SpO2.exe) that displays real-time SpO2, pulse rate, and waveform, plus a separate review program for reading saved session files.
Do I need to install a driver before using it?Â
Yes. Before running the software, install the USB-to-Serial CH340 driver on your PC if it isn’t already present, since the sensor communicates through a CH340 USB-TTL chip.
Can this sensor monitor more than one person at a time?Â
Yes. The software can display live parameters for up to 4 people at once, each in its own display panel.
How much data can the device store?Â
Each session can save up to 2 hours of continuous SpO2 and pulse rate data, saved both as a review file and as an Excel-readable text file.
Is this sensor reusable?Â
Yes. It’s a reusable adult finger clip sensor made of TPU, designed to be cleaned and disinfected between uses rather than discarded after one use.
What is the accuracy of the SpO2 and pulse rate readings?Â
SpO2 accuracy is ±2% under normal conditions (±3% during exercise or weak perfusion), and pulse rate accuracy is ±2 bpm normal (±3 bpm during exercise or weak perfusion).
What operating system does it support?Â
The included software is built for Windows PCs.
