Differential pressure measurement cluster
This cluster provides attributes and commands for configuring the measurement of differential pressure, and for reporting differential pressure measurements.
Differential pressure values are given in Pascal (Pa).
Periods other than time intervals used with Configuration reporting commands are given in millisecond (ms).
There are few arguments to configure to set correctly the device. A number of samples (configurable) is done at each measurement, the periodicity between each sample is configurable. If a measurement is attempt a threshold then a confirmation is done by a number of confirmation measurement. All these are resumed in the following graphism:
If a field of the payload starts with 0x, this means that it’s an hexadecimal representation, and if it starts with 0b, it is a binary representation.
Any multi-byte numerical value is serialized in “Big Endian” order.
- Measured value attribute
- Min measured value attribute
- Max measured value attribute
- Measurement period attribute
- Samples per measurement attribute
- Samples per confirmation measurement attribute
- Sampling period attribute
- Mean measured value since last report attribute
- Minimal measured value since last report attribute
- Maximal measured value since last report attribute
Measured value attribute
The Measured value attribute contains the last measured differential pressure value.
