Illuminance Measurement Cluster
This cluster delivers the illuminance measured by the remote sensor, and the minimum and the maximum values that it is capable to measure, and the minimumum and maximum measured since last power on or reset.
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 current concentration value measured by the device.
Notice that the Measured Value Attribute (0x0000) is the source of calculated attributes that keep currents Mean (0x0100), Minimal(0x0101) and Maximal(0x0102) values since startup or reset of the sensor. All these calculated attributes can be accessed the same way than the source one.
