Light sensensing module using CdS photo resistor as sensor for the

detection of light change. Sensitivity of light change can be adjusted by

a built-in variable resistor. It can be used as a door announciator if a

sounder is attached, as an intrusion alarm if light is interrupted, drawer

alarm if it is opened and light is detected etc.

1. Operating Voltage: 3.3V to 6V

2.Operating Current: 15ma (Low output )

2. Digital Output(D0): Low output

3. Sensitivity Adjustable Resistor  

4. Module Size: 3.2cm x 1.4cm
