Description

When there is light, the resistance of LDR will become low according to the intensity of light. The greater the intensity of light, the lower the resistance of LDR. The sensor has a potentiometer knob that can be adjusted to change the sensitivity of LDR towards light.

Features:

Able to detect ambient brightness and light intensity
Adjustable sensitivity (via blue digital potentiometer adjustment)
Operating voltage 3.3V-5V
Digital switching outputs (0 and 1) -D0
With fixed bolt hole for easy installation
Small board PCB size: 3cm * 1.6cm
Power indicator (Red) and the digital switch output indicator (Green)
Features wide range voltage comparator LM393
Pin outs:

External 3.3V-5V VCC
External GND ground
DO digital output interface, a small plate (0 and 1)
