sensor
Battery
Battery level
Bits [3:0]
Bits [7:4]
unsigned value
ν
, range 1 – 14;
battery voltage in V = (25 +
ν
) ÷ 10.
RFU
Temp(environment)
Temperature as measured by the digital sensor
Bits [6:0]
Bit [7]
unsigned value
τ
, range 0 – 127;
temperature in °C =
τ
- 32.
RFU
measurement range -32 to 95°C
RH
Relative humidity as measured by digital sensor
Bits [6:0]
Bit [7]
unsigned value in %, range 0-100.
The value 127 indicates measurement error.
RFU
CO
2
Equivalent CO
2
level as measured by digital sensor
Bits [15:0]
RFU
The value is always displayed as 0xffff because no
CO
2
sensor is installed in this module.
VOC
Total Volatile Organic Compound Level as measured by the digital sensor
Bits [15:0]
RFU
The value is always displayed as 0xffff because no
VOC sensor is installed in this module.
