MEASUREMENT ARCHITECTURE

Six parameters.
One environmental picture.

The current hardware design targets the following measurements. Sensor integration and complete system validation remain part of development.

Future expansion: CO, NO₂, SO₂ and O₃ sensing may be added. These gas channels are not included in the current design.

MEASUREMENTS WITH CONTEXT

More than a number.

The planned monitoring experience combines current readings, historical trends and alert conditions. A remote dashboard should make gaps and stale readings as visible as new measurements.

Live monitoring

Designed for periodic readings, device status and clear last-update timestamps.

Historical trends

Planned time-series views to compare readings across time and locations.

Alerts

Planned configurable thresholds, with notification delivery to be implemented.

AQI visualisation

An AQI view is planned once pollutant coverage, averaging periods and data quality support the selected method.

CURRENT DESIGN

Separate sensing.
Connected processing.

The sensor head is based on STM32G071. An RS485 link connects it with the ESP32 controller architecture. BME280 is selected for temperature, relative humidity and atmospheric pressure.

Wi-Fi and cellular connectivity are planned for the Air controller. MQTT/API ingestion and the live platform remain integration work.

ENGINEERING NOTES

Sensor head: STM32G071 + environmental sensors
Environmental sensing: BME280: temperature, humidity, pressure
Head-to-controller link: RS485 architecture
Controller: ESP32-based connectivity
Battery concept: Rechargeable 1-cell Li-ion; capacity to be defined

AQI, PRESENTED RESPONSIBLY

A concentration is
not an AQI score.

The preview deliberately leaves the national AQI score unavailable. Current PM2.5 and PM10 coverage alone does not meet the project’s minimum pollutant coverage for a national AQI result.

No certification, regulatory compliance or measurement accuracy is claimed.
