5.7.2 Ambient light sensor

The ambient light sensor TEMT6000X01 from Vishay Semiconductors is sensitive to

visible light much like the human eye. The measurement circuitry is configured to

measure the illuminance from ~10 to ~900lx when the internal VCC/1.6 reference is

used.

The data in Table 5-10 which shows the relationship between illuminance and output

voltage of the sensor circuitry is generated based on the symbols and formulas in

Table 5-9.
