Carbon Dioxide Sensor Channel

Channel Category: carbon_dioxide

Monitors CO₂ levels in the environment to track air quality and ventilation efficiency.

Required Properties

Property	Data Type	Range	Unit	Permissions
`detected`	`Bool`	`true/false`	-	RO (Read-Only)
`density`	`Float`	`0.0–100,000.0`	ppm	RO (Read-Only)

Property Details

`detected`

Indicates whether the sensor detects abnormal levels of carbon dioxide:

true: Abnormal CO₂ levels detected.
false: CO₂ levels have returned to normal.

`density`

Reports the current detected carbon dioxide (CO₂) level in parts per million (ppm).

[!Notes]: Either detected or density must be included, depending on the use case. If only density is provided, values of 800 ppm or higher are generally considered poor air quality and will be displayed as a warning.

Optional Properties

Property	Data Type	Range	Unit	Permissions
`peak_level`	`Float`	`0.0–100,000.0`	ppm	RO (Read-Only)
`active`	`Bool`	`true/false`	-	RO (Read-Only)
`fault`	`Uchar`	`0–255`	-	RO (Read-Only)
`tampered`	`Bool`	`true/false`	-	RO (Read-Only)

Property Details

`peak_level`

Indicates the highest carbon dioxide (CO₂) level detected by the sensor, in parts per million (ppm).

`active`

Indicates the channel’s current working status:

true: The sensor is active and functioning correctly.
false: The sensor is inactive or non-functional.

`fault`

Represents the fault state of the sensor:

0: No fault detected.
Non-zero: A fault has been detected, potentially affecting functionality.

`tampered`

Indicates whether the channel has been tampered with:

true: The channel has been tampered with.
false: The channel is in a normal, non-tampered state.
