2.6.1.4. U7 : Light Sensor
Bellow is comparison between luminance and out current. We used BH1600FVC (Rohm)
The Output voltage is caculated as below
Viout = 0.6 x10-6 x Ev x R1
Where, Viout = IOUT output voltage [V]
Ev = lilluminance of the ALS(Ambient Light Sensor) surface [lx]
R1 = IOUT output resistor [Ω]
