Visible Light Sensor

PROD Model:φ5

Maximum Applied Voltage: the maximum voltage that can be continuously applied to a component in the dark

Dark Resistance: resistance value at 10 seconds after 10Lux illumination is turned off

Maximum Power Consumption: maximum power consumption when the ambient temperature is 25 ° C

Bright Resistance: after 2 hours of exposure with 400-600Lux light, the test value under 10Lux light of standard light source (color temperature 2856K)

γ Value: logarithm of the ratio of the standard resistance value at 10Lux illuminance to 100Lux illuminance

γ= Lg(R10/R100) /Lg (100/10) =Lg(R10/R100)
