Indoor simple PM10 chart card with background

Who it’s for

Facility managers, building managers, and indoor air quality specialists ask “can I see PM10 trend and severity at a glance?” The background variant combines a compact sparkline with a full-card color signal for wall-mounted displays.

What it does

A sensor reporting pm10 = 25 µg/m³ renders a compact sparkline-style trend line and the current value on a card whose entire background fills with the severity color: light green for Good (0–50 µg/m³), orange for Moderate (50–150 µg/m³), and red for High (above 150 µg/m³).

• Full-card background color makes PM10 severity readable across a room without reading the number
• Compact sparkline chart shows PM10 direction at a glance in a space-efficient layout
• Shows one sensor’s data per widget; add multiple widgets to monitor different rooms side by side

How to set up

Data keys

Key	Role	Type	Description
pm10	Chart series	Timeseries	PM10 concentration in µg/m³; change the key name to match your device’s telemetry key
Latest	Latest value	Timeseries	The headline figure above the chart. Its own color ranges are where the band colors are edited

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 the color ranges on the Latest data key.
• To change the background colors — edit the color of each range on the Latest data key.
• To rename the units label — change the Units field in the widget settings if needed.

Tips

• On a wall display, the colored background announces PM10 severity from across the room while the sparkline shows whether the level is stable, rising, or recovering.
• Use this card when you need both a trend signal and at-a-glance status in a compact footprint — for example, one card per meeting room in a corridor display.
• Use consistent severity colors across all indoor air quality widgets: light green is safe, red needs action.
