The AirQ is a low-power air quality monitoring device that provides detailed air quality insights. It has several components, including the SEN55 air quality sensor and the SCD40 CO2 sensor, which measure PM1.0, PM2.5, PM4, PM10 particles, temperature, humidity, VOC, and CO2 levels. It works with the StampS3 main controller and features 8M Flash memory for data processing and storage.

The device includes a 1.54" e-ink display with a 200 x 200 resolution, offering a clear view of the data. This display retains the final data screen even during power outages, providing uninterrupted visualisation. To improve monitoring duration, the AirQ comes with a 450mAh battery and an RTC low-power power management circuit. This design allows the device to enter sleep mode and wake up on a schedule, conserving energy and extending battery life.

AirQ's firmware is preconfigured to upload data to M5's EZDATA cloud platform, which automatically creates monitoring pages for convenient remote access and data management. You can access air quality data anytime and anywhere via this cloud-based system.

For flexible installation, AirQ includes LEGO mounting holes, adhesive magnets, and four detachable mounting ears. This supports secure installation in various environments such as homes, schools, industrial facilities, and hospitals, providing continuous online air quality monitoring.

Note: To enter download mode, press and hold the G0 button on the StampS3 before powering on, and release it after powering up.

Power On:

You can power on the device by pressing the "WAKE" button or through the RTC-triggered IRQ signal for wake-up. After completing the wake-up signal, in the program initialisation, it is necessary to set the hold (G46) pin to a high level (1) to maintain power; otherwise, the device will re-enter sleep mode.

Power Off:

To power off when not externally powered via USB, press the RST button. Alternatively, when running the program without external USB power, set HOLD (GPIO46) to 0 to achieve a power-off shutdown.
