一覽

Air quality monitoring systems measure pollutants (PM2.5, PM10, NO2, O3, CO) via sensors, transmit data wirelessly, and visualize/alert on exceedances. Requires hardware integration (Arduino, Pi, IoT devices), environmental science basics, and data pipelines. Used in: smart city platforms, industrial compliance, health apps, research networks. Career path: IoT engineer → environmental data specialist → sustainability architect. Growing field: 2026 demand driven by ESG reporting, regulatory compliance (EPA, EU directives), and health-conscious cities.

什麼是 Air Quality Monitoring

Air quality monitoring is the measurement and tracking of airborne pollutants: particulate matter (PM2.5, PM10), gases (NO2, O3, CO), and other indicators. Systems integrate sensors, wireless transmission, data storage, and visualization to provide real-time or near-real-time air quality intelligence. Applications: smart cities (public health warnings), industrial sites (EPA/EU compliance), research networks (atmospheric science), and consumer apps (personal exposure alerts). Data is typically stored in time-series databases (InfluxDB) and visualized in dashboards (Grafana, custom web apps).

❓ 常見問題

What's the difference between PM2.5 and PM10 sensors?
PM2.5 measures particulate matter <= 2.5 micrometers (enters lungs). PM10 measures <= 10 micrometers (respiratory system). PM2.5 is more relevant for health; PM10 for industrial compliance. Most systems measure both.
How accurate are consumer air quality sensors?
Consumer-grade sensors (DHT22, SDS011) are accurate +/- 10-15% vs. reference grade. Sufficient for trending and alerts, not for regulatory compliance. Professional sensors cost 5-10x more but are certified.
Should I use WiFi, Bluetooth, or MQTT for transmission?
MQTT is best for IoT networks (low bandwidth, battery-friendly). WiFi for local/indoor. Bluetooth for personal devices. LoRaWAN or NB-IoT for large-scale city networks with poor connectivity.
What's a typical air quality monitoring deployment?
Sensor + microcontroller (Arduino/Pi) running at 10-min intervals → MQTT broker (Mosquitto) → InfluxDB time-series store → Grafana dashboard + alerts. Cost: $200-500 per sensor node. Maintenance: calibration every 6-12 months.
Is air quality monitoring regulated?
Yes. EPA (USA), EASA (Europe), and local authorities set standards. If you're providing public data, follow regional guidelines. Private/internal monitoring is less regulated but should still follow best practices.
How do I calibrate air quality sensors?
Factory calibration is included. Drift occurs over time. Recalibrate by co-locating with a reference-grade sensor for 1-2 weeks and applying a linear correction. Some sensors auto-calibrate via firmware.
What's the career progression in air quality monitoring?
IoT technician → environmental data engineer → sustainability/ESG manager. ESG reporting is growing: expect air quality data requests from investors, regulators, and compliance teams. Solid upside.
