ITEM NAME:10 pcs light depends on the resistance of the LDR photoresistance GL5528. N1H7 10 pcs light depends on the resistance of the LDR photoresistance GL5528. N1H7 The photocell is generally used to take the measurement of photosensitive resistance, light control and photoelectric conversion (turns light into electricity). The value of resistance of light change depending on the variation of the resistance of incident radiation (visible), or in.The value of resistance of light change depending on the variation of the resistance of incident radiation (visible), or in conditions of darkness, its resistance to 1, when light conditions, it retains that resistance 10-20KÃŽ ©.
