Sulphur Dioxide Sensor Channel

Channel Category: sulphur_dioxide

Measures sulphur dioxide (SO₂) levels in the air for environmental monitoring.

Required Properties

Property	Data Type	Range	Unit	Permissions
`detected`	`Bool`	`true/false`	-	RO (Read-Only)
`density`	`Float`	`0.0–100,000.0`	µg/m³	RO (Read-Only)
`level`	`Enum`	`low/medium/high`	-	RO (Read-Only)

Property Details

`detected`

Indicates whether the sensor detects abnormal levels of sulphur dioxide:

true: Abnormal SO₂ levels detected.
false: SO₂ levels are within normal limits.

`density`

Reports the current sulphur dioxide concentration:

Measured in micrograms per cubic meter (µg/m³).
Reflects real-time SO₂ levels in the environment.

`level`

Provides a qualitative assessment of sulphur dioxide levels:

Possible values:
- low: Safe SO₂ levels.
- medium: Moderate SO₂ levels that may require attention.
- high: High SO₂ levels, potentially hazardous to health.
The level property will be mapped to specific density ranges:
- low: 0–20 µg/m³
- medium: 21–75 µg/m³
- high: >75 µg/m³

[!Notes]: At least one of the required properties (detected, density, or level) must be present. Additionally, either density or level can be provided, but not both simultaneously.

Optional Properties

Property	Data Type	Range	Unit	Permissions
`active`	`Bool`	`true/false`	-	RO (Read-Only)
`fault`	`Uchar`	`0–255`	-	RO (Read-Only)
`tampered`	`Bool`	`true/false`	-	RO (Read-Only)

Property Details

`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.
