Indoor PM10 card

Who it’s for

Facility managers, building managers, and indoor air quality specialists ask “is the PM10 particulate level in this space currently safe for occupants?” They monitor coarse particulate matter to protect building occupants — particularly those with respiratory conditions — and to detect unusual dust events such as construction activity or HVAC filter failures.

What it does

A sensor reporting pm10 = 25 µg/m³ displays the reading on a color-coded card: light green for Good (0–50 µg/m³), orange for Moderate (50–150 µg/m³), and red for High (above 150 µg/m³).

• Live PM10 reading in µg/m³ with automatic color coding across three severity bands
• Severity bands reflect typical indoor air quality guidelines for coarse particulate matter
• Shows one sensor’s reading per widget; add multiple widgets to monitor different rooms or zones

How to set up

Data keys

Key	Role	Type	Description
pm10	Main value	Timeseries	PM10 concentration in µg/m³; change the key name to match your device’s telemetry key

The widget ships with a simulated function datasource key labeled PM10, so it draws random values until you point the datasource at a device and rename the key.

To point it at your own device: open the dashboard in edit mode, open the widget’s Datasources, pick the entity or entity alias, and replace the function key with the key your device reports.

Value ranges

Range (µg/m³)	Level	Color
0–50	Good	Light Green
50–150	Moderate	Orange
150+	High	Red

How to customize

• To change the severity thresholds — edit Icon color ranges and Value color ranges; set the same boundaries in both so the icon and the number always agree.
• To change the band colors — edit the color of each range in Icon color ranges and Value color ranges.
• To rename the units label — change the Units field in the widget settings if needed.

Tips

• PM10 spikes in an office building often trace to HVAC filter failures, nearby construction, or occupants bringing in dust on clothing after outdoor work; a sharp rise during normally clean periods warrants an inspection of the fresh-air intake and filter status.
• In spaces where cleaning is done with dry methods (sweeping, vacuuming without HEPA filtration), PM10 can temporarily exceed 150 µg/m³; scheduling cleaning during unoccupied hours and confirming levels return to Good before occupants arrive protects respiratory health.
• For HVAC commissioning and filter change scheduling, archive the monthly average PM10 readings; a gradual upward drift over weeks indicates filter clogging before the pressure drop alarm triggers.
