See your air. AirCube is a desktop air quality monitor with built-in Home Assistant support over Zigbee or Bluetooth (BLE). Every model tracks temperature, humidity, eCO2, eTVOC, and VOC Level; AirCube Pro also measures true CO2 and ambient light. A glanceable LED shows the current air quality.

Works standalone out of the box. Pairs with Home Assistant in minutes. Other platforms are supported through community-contributed extensions.

AirCube: common questions

What microcontroller does the AirCube use?

The AirCube is built around the ESP32-H2-MINI-1, from the ESP32 family.

How big is the AirCube PCB?

The AirCube measures 45 × 45 mm, has 2 copper layers and is 1.66 mm thick.

How many components are on the AirCube?

52 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the AirCube design files?

From the StuckAtPrototype/AirCube repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the AirCube design in my own project?

Yes, under the terms of its Apache-2.0 license, which StuckAtPrototype chose for the repository.

Can I test firmware for the AirCube without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
