Easy Light Dependent Resistor Module(ST1107)

1 Introduction

Light Dependent Resistor, also called photo-resistor, are light sensitive devices most

often used to indicate the presence or absence of light, or to measure the light

intensity. It’ similar with the Light Dependent Resistor Module (SE012), the difference

is that this module has one indicator light, which would be on when this module’s

voltage signal is changed. And, this module has integrated 3-pin terminal, which can

be simply and tidily connected with Arduino sensor expansion board, like the following

picture:

Specification

 Operation voltage: 5V

 With 3-pin Jumpers

 Size: About25*15mm

 Weight: 4g
