Latest sensor values

PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).

What the data includes

The Saint‑Sauveur air‑quality feed includes five recent observations from a single monitoring site, covering five measured variables: PM1, PM2.5, relative humidity, temperature and the particle count UM003. All of the latest readings were recorded at the same moment – 2026‑02‑10 22:00 UTC – so the dataset is uniformly fresh across every pollutant.

For each parameter the reported range collapses to a single value, meaning the minimum, median and maximum are identical. PM1 registers 6.50 µg/m³, while PM2.5 shows 7.27 µg/m³; relative humidity sits at 53.36 %, temperature is –8.50 °C and UM003 records 946.60 particles per cubic centimetre. Because the spread is zero, there is no observed variability within this snapshot.

The coverage is limited to one station, so spatial differences across Saint‑Sauveur are not captured in these data. Although the timestamps are recent, the lack of multiple sites or repeated measurements means that short‑term fluctuations cannot be seen here. Consequently, while the current values give a precise picture of conditions at the monitoring point on 2026‑02‑10, they do not reflect possible changes elsewhere in the city or over longer periods.
