PolluSensWeb: Visualize Your Air Sensor Data Right in the Browser

polluSensWeb is here to decode the bytes, draw the graphs, and help you breathe easy.
It is a lightweight, browser-based tool that talks directly to your UART air quality sensors (PM2.5, VOCs, temperature, humidity, etc). No installs, no drivers — just plug it in and open the page.

Imagine you’ve got an air quality sensor on your desk. It’s plugged in over USB, spitting out numbers through a UART connection. You want to see what it’s saying—PM2.5, VOCs, maybe some temperature data—but you don’t want to dig through hex dumps or write a bunch of code just to see a simple chart.

That’s exactly why polluSensWeb exists.

You open a web page. That’s it. No drivers. No apps. No command lines. Just Chrome or Edge or any browser that supports Web Serial. You pick your sensor from a dropdown, and instantly, your data comes alive. 

It reads raw binary frames, it logs every packet (make byte stuffing if needed) so you can peek under the hood. Want a chart with red for PM2.5 and blue for PM10 on the same chart? Just check a few boxes. Want to tweak the tension or line width?

 Click “Save CSV” and walk away with a full log—timestamps and all data.

It’s open-source, offline-friendly, and small enough to run on an old PC. Everything happens in your browser. 

Tinkering with sensors, wanting a faster way to see what’s really in the air around you?

So go ahead. Plug in a sensor. Open the browser and watch the air data come to live charts.
