See changes as they happen
Most air quality sensors bury you in numbers and charts.
AirCube does the opposite. It turns invisible air changes into a simple color signal you can understand at a glance, so you know when to act.
You’ll start to notice patterns in how everyday activities affect your air within seconds.
Indoor air changes more than we think
Everyday activities like cooking, cleaning, soldering, or working in a closed room can raise levels of volatile organic compounds (VOCs) without any obvious smell.
When these changes build up, many people notice it as poor focus, fatigue, or just feeling “off” long before they realize the air is stale.
AirCube makes these invisible shifts visible.
As VOC levels rise, its color changes, giving you a simple cue to open a window, ventilate, or take a short break.
Cleaner air often means a clearer head and a more comfortable space to work in.
Why it exists
Most air quality monitors expect you to interpret VOC values, CO₂ equivalents, or AQI scales.
Unless you’re a specialist, it’s hard to know what those numbers actually mean.
AirCube was built to remove that friction. It translates complex air data into a soft color glow that anyone can read instantly.
No charts. No dashboards. No mental math.
Built on real engineering
At its core, AirCube runs on proven, industrial-grade components:
- ENS161 sensor for detecting VOC changes
- ENS210 sensor for temperature and humidity stabilization
- ESP32-H2 microcontroller for reliability and hackability
- Addressable RGB LEDs for smooth, natural color transitions
This combination provides stable readings with low power draw.
AirCube is fully open-source and designed to be both a practical daily tool and a platform for experimentation.

We make our own products
AirCube is not a rebranded gadget.
It was designed, engineered, and assembled by the same small team that supports it.
That means:
- Hardware and firmware are built together, not outsourced
- Updates and fixes come from the people who made it
- Support emails go to the maker, not a ticket system
AirCube is also fully open-source. All hardware and firmware are available if you want to inspect, modify, or build on it.
If something feels unclear or off, you are talking directly to the person responsible for the product.
