PolluSensWeb: Visualize Your Air Sensor Data Right in the Browser
polluSensWeb is a lightweight web-based serial interface and charting tool for visualizing and logging data from UART pollution sensors (PM2.5, VOC, 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. Connect the sensor, pick your sensor from a dropdown, and instantly, your data comes alive.
It reads raw binary frames, it logs every packet (makes 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. 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.
Live version (Chrome, Edge, Opera):

More sensors are coming to the default JSON :), but you can already add your custom right away!

UPD: polluSensWeb just gained a powerful new feature - HTTP webhook support.
The app can now push every parsed sensor frame directly to any endpoint you choose, using customizable headers and JSON body templates.
The coolest part: both headers and body support placeholders (e.g., {{field:PM2_5}}, {{ts}}, or full field loops), letting you map sensor data into any API format without touching the code. This makes it dead-simple to forward PM readings into home automation systems, databases, online dashboards, or your own custom server.
Webhook requests can be triggered on every packet or at a user-defined interval, and a built-in “Test Send” button helps verify output instantly.
In short: your DIY air sensor can now talk to anything on the internet, no extra coding and SW needed.
