Features:-

• Can detect ambient brightness and light intensity
• Adjustable sensitivity (via blue digital potentiometer adjustment)
• Operating voltage 3.3V-5V
• With fixed bolt hole for easy installation
• Small board PCB size: 3cm * 1.6cm
• Power indicator (red) and the digital switch output indicator (green)
• Using LM393 comparator chip, stable

out pins:-

• External 3.3V-5V VCC
• External GND GND
