Description

Air Quality is an integrated, low-power air quality monitoring device designed to provide comprehensive air quality monitoring solutions. It features multiple components, including the SEN55 air quality sensor and the SCD40 CO2 sensor, enabling the monitoring of PM1.0, PM2.5, PM4, PM10 particles, temperature, humidity, VOC, and CO2 concentrations. Powered by the StampS3 main controller and equipped with 8M Flash memory, Air Quality ensures efficient data processing and storage capabilities.

The device comes with a 1.54-inch e-ink display with a resolution of 200x200, providing a clear visual representation of the data. Even in the event of a power outage, the final data screen will remain visible, ensuring continuous visualization. To extend monitoring capabilities, Air Quality is equipped with a 600mAh battery and an RTC low-power power management circuit. This allows the device to enter sleep mode and be awakened on a scheduled basis, conserving energy and prolonging battery life.

Out of the box, Air Quality's firmware is preconfigured to upload data to M5's EZDATA cloud platform, which automatically generates monitoring pages, providing users with convenient remote access and data management. Users can monitor air quality data anytime, anywhere through the cloud-based access.

For versatile installation options, Air Quality features LEGO mounting holes, adhesive magnets, and four detachable mounting ears. This allows for flexible and secure installation in various settings, including homes, schools, industrial facilities, and hospitals, enabling long-term online air quality monitoring.

Download Mode
To enter download mode, power off the device first, then insert the USB while holding down the BooT button on StampS3 or the G0 key on Air Quality, and then release it after power is turned on.

Power on and off
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 initialization, 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.
