 Refer to 6.6.7 Data Conversion about how to convert to analog data to temperature and
illumination
6.6.7 Data Conversion
6.6.7.1 Analog Data Format
Analog data from temperature sensor and illumination sensor are a combination of 16-bit hexadecimal
integer between 0~2EE0(0~1200.0mV) which unit value corresponds to 0.1 mv.
6.6.7.2 Conversion of Analog Data
 Conversion of Analog Data to Actual Voltage
If the Value is between 0 ~ 7FFF, Voltage (mV) = Value * 0.1
If the Value is between 8000 ~ FFFF, Voltage (mV) = (Value – 65536) * 0.1
 Conversion of Actual Voltage to Temperature
Temperature(℃) ={ Volt(mV) -600(mV)} * 0.1(℃/mV)
 Conversion of Actual Voltage to Illumination
Illumination(Lux) = Volt(mV) * 0.25(Lux/mV)
