5.7.2 Ambient light sensor
14
Atmel AVR1923
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
voltage of the sensor circuitry is generated based on the symbols and formulas in
