Automated environmental monitoring
Know changes early.
Stay in control of every decision.
SITECH automated monitoring stations track water and air quality continuously — timely alerts when indicators exceed thresholds, AI-based WQI/AQI forecasting, everything managed in Vietnamese-language software.
Why continuous monitoring is needed
One water sample, one moment in time — not enough.
A single sampling result at a single moment can hardly reflect the full behaviour of a whole river. Automated monitoring adds an important layer of information between sampling rounds: how indicators are changing, when an anomaly began, and which point to check first.

of Nhuệ River monitoring points rated poor to very poor, with WQI around 10–25 and more than 2,500 major discharge sources.

Monitoring software
Data doesn’t sit in a filing cabinet.
It sits on your screen.
Green Solution software comprises 3 tools: a public information portal for residents and businesses, a mobile app (iOS, Android) and internal operations software for regulators.
- Station list, distribution map, pollution rankings — colour codes from green (no pollution) to brown (most severe pollution)
- Hourly or daily charts; readings above the safety threshold shown in red
- Alerts via website, mobile app and SMS when an indicator changes abnormally
- Access permissions by user role
- Remote operation: change measurement/sending frequency, change alert thresholds, clean sensors (surface-water line)
AI forecasting
WQI / AQI forecasting — to prepare, not to guess.
The system analyses historical monitoring data to forecast water quality (WQI) and air quality (AQI) trends at each measuring point — supporting alert preparation, activity planning and response plans based on expected trends. WQI calculation and publication follow the method and parameter set in QCVN 08:2023/BTNMT and Decision 1460/QĐ-TCMT (VN_WQI).
Water quality forecasting. Already applied at the Hội An water monitoring station.
Air quality forecasting for air stations and dust monitors.
Forecast scope, horizon and accuracy depend on the data and model validation results at each point. AI supports managers; it does not replace on-site verification.

Frequently asked questions
Straight questions, honest answers.
Does an automated station replace manual sampling?
No. An automated station supports continuous tracking; it does not automatically replace all sampling and analysis required by regulation. It adds a layer of information between sampling rounds — and when data is used for specialist reporting or official publication, the monitoring method must be defined in advance and data quality assured as required.
How accurate is AI forecasting?
Forecast scope, horizon and accuracy depend on the data and model validation results at each monitoring point. SITECH agrees the application approach with the user according to specific conditions. AI supports managers; it does not replace on-site verification.
What if power or network is lost?
The main product lines have backup power for up to 30 days without sunshine (dust monitor: 3 days). The system can back up and preserve data on power loss.
Will our data be made public?
No. The public information portal only publishes data measured, verified and approved for publication by state agencies. A unit’s operational data is access-controlled by user role.
Where can a station be installed?
The installation site needs coverage (3G/4G, LoRa or WiFi depending on the line). For surface-water stations, coverage, buoy anchoring, flood risk, and sensor cleaning and calibration arrangements must be assessed. SITECH surveys before installation.
What about warranty and maintenance?
SITECH provides a 1-year system warranty; sensors follow the manufacturer’s warranty policy. In-country resources for maintenance, repair and upgrades.
