DS1340 Crystal Specifications
2.4.5.5. Temp Sensor
AD0(PC0)에 National LM50
2.4.5.6. Light Sensor
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]
