Horizontal volatile organic compounds card with background

Who it’s for

Indoor air quality managers, building managers, and health and safety officers ask “can I monitor VOC levels across many rooms in a compact layout where the severity is still instantly visible?” The horizontal background variant combines space efficiency with the full-card color signal.

What it does

A sensor reporting voc = 320 ppb displays the reading in a horizontal card whose entire background fills with the severity color: green for Good (0–500 ppb), orange for Moderate (500–1000 ppb), and red for Hazardous (above 1000 ppb).

• Full-card background color makes VOC severity readable across a room without reading the number
• Horizontal layout fits more rooms per row on a multi-zone indoor air quality dashboard
• Shows one sensor’s reading per widget; tile multiple widgets to monitor all rooms and zones at a glance

How to set up

Data keys

Key	Role	Type	Description
voc	Main value	Timeseries	VOC concentration in ppb; change the key name to match your device’s telemetry key

The widget ships with a simulated function datasource key labeled VOCs, 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	Level	Color
0–500	Good	Green
500–1000	Moderate	Orange
1000+	Hazardous	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 background colors — edit the background color for each severity level in the widget settings.
• To rename the units label — change the Units field in the widget settings if your sensor reports in µg/m³.

Tips

• A row of horizontal background cards, one per room, lets the facilities manager see which spaces are elevated immediately after a cleaning or renovation event without scanning individual numbers.
• Use consistent severity colors across all indoor air quality widgets: green is safe, red needs action.
• For health and safety audits, the color-coded row provides an instant whole-floor snapshot that is easier for non-technical inspectors to interpret than a table of numbers.
