Photoresistance Sensor Module — LDR Light Sensor

This Light sen­sor mod­ule uses a photodetectorGL5528 to detect the light inten­si­ty of the envi­ron­ment. As the resis­tance of the sen­sor varies depend­ing on the amount of light it is exposed to, the out­put volt­age changes with the ligth intensity.This mod­ule out­puts both ana­log and dig­i­tal sig­nals, which can be used to trig­ger oth­er modules.Also, the pro­ten­tiome­ter can be used to adjust the sen­si­tivety of dig­i­tal out­put. The dig­i­tal ter­mi­nal out­put HIGH when the ligth inten­si­ty exceeds the val­ue set by poten­tiome­ter, and vice ver­sa. The out­puts of ana­log tern­i­mal increase with the light inten­si­ty.FeaturesVoltege:3.3V~5VOut­put: Both ana­log and digtal(0 or 1)
