Smart Indoor Air Quality Monitoring
Discover how OOS enables secure, centralized air quality monitoring with support for PM2.5, CO₂, TVOC, and more. Fully compliant with Taiwan's IAQ law and ready for smart building integration.
Smart IAQ Deployment in a Major Hsinchu Department Store
A major department store in Hsinchu, with multiple floors and heavy daily foot traffic, faced growing pressure to improve air quality transparency. Indoor Air Quality (IAQ) directly affects customer experience and employee health, and under Taiwan's Indoor Air Quality Management Act, public venues are required to monitor, disclose, and take action on IAQ data in real time.
However, the existing monitoring setup posed several limitations:
- Sensors were deployed in isolation, lacking centralized control
- Data was transmitted via public networks, putting sensitive environmental data at risk
- There was no real-time alert or backup mechanism in place
- The monitoring system could not interface with air-conditioning controls
To solve this, we deployed OOS alongside ChuanYu's Air Quality sensors (AirBox) to create a fully encrypted, end-to-end monitoring infrastructure — one that securely delivers sensitive data and remains completely invisible to the public internet.
Before & After
| Feature | Before OOS | After OOS |
|---|---|---|
| Data Transmission | Unencrypted data sent over public networks; vulnerable to interception | Secure end-to-end encryption over mobile networks via OOS; no exposure to internet |
| System Visibility | Devices addressable via public IPs or manual login | All devices hidden behind NAT; never exposed to public IP space |
| Management & Monitoring | Data scattered across isolated sensors | Centralized platform securely aggregates and visualizes IAQ data in real time |
Measured Parameters
The AirBox system supports real-time monitoring of key indoor air quality indicators:
- PM2.5 / PM10 – Fine and coarse particulate matter
- CO₂ – Carbon dioxide concentration
- CO – Carbon monoxide levels
- TVOC – Total Volatile Organic Compounds (12 harmful gases)
- HCHO – Formaldehyde levels
- O₃ – Ozone exposure
- Temperature & Humidity – Ambient environmental factors
All data is transmitted securely, never touching the open internet.
Benefits of OOS
- Full Data Privacy by Design – All data is encrypted in transit, never exposed online — even during multi-site transmission.
- Zero Network Exposure – Devices operate under NAT with no public IPs, eliminating attack surface and external visibility.
- Regulatory & ESG Compliance – Enables transparent IAQ governance in line with Taiwan's IAQ law and corporate sustainability goals.
- Faster, Safer Incident Handling – Live alerts and encrypted failover prevent data loss and reduce operational risks.
- Scalable Automation-Ready Platform – Future-proof interface allows seamless connection to HVAC and smart building systems — without compromising security.
