12.2 Command mode
In a single sensor configuration this mode allows a transmission of the measured values with maxi-
mum speed and no protocol overhead. The measuring type cannot be changed in this mode. It must
be set before using the button.
There are eight commands with one byte for master sensor communication.
0xYZ means: this is one byte with the hexadecimal value of YZ

2 Byte binary
Hi Byte (data: Bit 0..4, Bit 7 = 1)
Low Byte (data: Bit 0..4, Bit 7 = 0)
Sensor sends continuously data until the
sensor receive 0xFF or 0x08
