Singapore Air Quality, PSI, UV & Dengue Alerts

Live Singapore environmental data in one Actor — pulled from the official NEA real-time feeds on data.gov.sg. Get PSI and PM2.5 by region (with health bands), the national UV index, and every active dengue cluster (case counts + location) — as clean JSON, CSV or Excel. Schedule it to power alerts, dashboards and monitoring. No key, no login.

Great for facilities & construction, outdoor/events, health analytics, travel and smart-city apps.

What you get

• 🌫️ PSI — 24h PSI per region (west/east/central/south/north/national) + health band, and the pollutant sub-indices (PM2.5, PM10, O₃, NO₂, SO₂, CO)
• 😷 PM2.5 — 1-hour PM2.5 per region
• ☀️ UV index — latest national UV reading + band
• 🦟 Dengue clusters — active clusters with locality, total case size, breakdown (homes / public places / construction sites) and centroid coordinates
• 🧾 Provenance — feed, timestamp, sourceUrl, collectedAt on every row
• ⏱️ Monitor-friendly — schedule it and each run appends a timestamped snapshot

Each row carries a feed field; the other fields depend on which feed produced the row.

FAQ

How current is it? The NEA feeds update in near real time; timestamp is the reading time and collectedAt is your pull time.

What are the PSI bands? Good (0–50), Moderate (51–100), Unhealthy (101–200), Very Unhealthy (201–300), Hazardous (300+).

Can I get alerts? Schedule the Actor and compare each snapshot — e.g. notify when PSI enters "Unhealthy" or a new dengue cluster appears.

How does billing work? A tiny per-feed fetch charge plus pay per reading returned.

Can I integrate this with other tools? The Singapore Environment Scraper can be connected with almost any cloud service or web app thanks to integrations on the Apify platform. It works with Make, Zapier, Slack, Airbyte, GitHub, Google Drive and many more, plus the Apify API, JavaScript/Python clients and MCP. Or use webhooks to trigger an action whenever a run finishes.

Original clean-room implementation using Singapore's official NEA open data (data.gov.sg), reused under the Singapore Open Data Licence. Not affiliated with or endorsed by NEA or the Singapore Government.

You pay only for what the run returns. Set a maximum cost per run and it stops cleanly at that limit.
