Indoor horizontal PM10 card

Who it’s for

Facility managers, building managers, and indoor air quality specialists ask “what is the PM10 level in this space right now?” They need a compact, space-efficient card that fits into multi-room air quality dashboards without dominating the layout.

What it does

A sensor reporting pm10 = 25 µg/m³ displays the reading in a horizontal card whose label and value sit side by side, color-coded by severity: light green for Good (0–50 µg/m³), orange for Moderate (50–150 µg/m³), and red for High (above 150 µg/m³).

• Horizontal layout fits more rooms per row on a multi-zone air quality dashboard
• Live PM10 reading in µg/m³ with automatic color coding across three severity bands
• Shows one sensor’s reading per widget; tile multiple widgets to monitor all rooms at a glance

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

• Use the horizontal layout to fit more rooms per row when building a whole-building PM10 overview; pair with the standard card for rooms adjacent to construction or high-traffic areas where PM10 is more likely to spike.
• Placing horizontal cards for PM10 and PM2.5 on the same row lets facility staff quickly assess whether a particulate event is coarse dust (PM10 elevated, PM2.5 stable) or fine combustion particles (both elevated).
• For post-renovation handover inspections, a row of horizontal PM10 cards across all affected spaces provides a quick confirmation that dust levels have returned to Good before occupants return.
