Pressure Measurement Cluster
This cluster delivers the Pressure of the remote sensor, and the minimum and the maximum values that it is capable to measure.
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
The Measured value information attribute set contains the attribute representing the pressure of the device.
