Visible Light Sensor

PROD Model:φ12

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

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)


A photoresistor is a resistance made of a semiconductor material whose conductivity changes with the change of illuminance. This
feature is used to make photoresistors of different shapes and
light-receiving areas. Photoresistors are widely used in toys, lamps,
cameras and other industries.


Epoxy encapsulation

Good reliability

Small size

High sensitivity

Fast response

Good spectral characteristics





They are also used in some dynamic compressors together with a small incandescent or neon lamp, or light-emitting diode to control gain reduction. A common usage of this application can be found in many guitar amplifiers that incorporate an onboard tremolo effect, as the oscillating light patterns control the level of signal running through the amp circuit.
