Permission: A user role of Project Developer or higher.
Single sensor card
To show CO2 readings on a single sensor card, use a CO2 sensor.
In a 1x1 view, the card displays the current CO2 readings in PPM, along with Temperature and Humidity readings.
If expanded, the graph type depends on the view you choose. By clicking the three dots, you can change the view to:
- Heatmap
- Time series
In the heatmap view, the x-axis displays dates while the y-axis represents hours. Colors indicate CO2 levels:
- Cool colour tones (green) = good or excellent levels
- Warm colour tones (yellow/red) = acceptable/mediocre or unhealthy levels
The scale ranges from 0 to 2000 PPM, with levels categorized as follows:
- 0 to 800 PPM indicates good or excellent levels
- 800 to 1500 PPM is considered acceptable or mediocre
- Levels above 1500 PPM are regarded as unhealthy
To toggle the display of the sensor's current readings, click the three dots and select "Hide/Show Sensor Status" on the upper right side of the card.
In the time series, the x-axis displays dates while the y-axis represents PPM levels. The line on the graph shows only CO2 readings. To display temperature or humidity readings, visit: How to display temperature and humidity readings from CO2 sensors on Dashboard graphs.
