Overview

Carbon Dioxide Concentration Measurement Cluster (0x040D)

Provides attributes for reporting Carbon Dioxide (CO2) concentration measurements and level indications in air, water, or soil. This cluster is a derived cluster from the base Concentration Measurement cluster specification.

Supports two main measurement modes:

• NumericMeasurement: Provides actual measured values in configurable units
• LevelIndication: Provides coarse level indication (Unknown, Low, Medium, High, Critical)

Specification: Matter 1.4 § 2.10 (Concentration Measurement)
