Description: LDR Module Circuit Photoresistor Light Dependent Resistor LDR 

LDR Sensor Module 3 Pin DC 3.3-5V Photoresistor Photo Cell Light Dependent Resistor LDR Sensor For Night Light Street Light Sensor Automatic Headlight Dimmer Control Photo Light Resistor

We are the leading suppliers for LDR Sensor Module. he LDR Sensor Module is used to detect the presence of light  measuring the intensity of light. The output of the module goes high in the presence of light and it becomes low in the absence of light. The sensitivity of the signal detection can be adjusted using potentiometer.

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

Specifications:

• Operating voltage 3.3V-5V
• Output Type Digital – Logic High or Low.
• Power indicator (red) and Output Indicator LEDs.
• Sensitivity can be adjusted using the on board potentiometer

Output Type:

• Analog voltage output -A0
• 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)
• Using LM393 comparator chip, stable

How it works:

• 1. Module light conditions or light intensity reach the set threshold, DO port output high when the external ambient light intensity exceeds a set threshold, the module D0 output low;
• 2. Digital output D0 directly connected to the MCU, and detect high or low TTL, thereby detecting ambient light intensity changes;
• 3. Digital output module DO  can directly drive the relay module, which can be composed of a photoelectric switch;
• 4. Analog output module AO and AD modules can be connected through the AD converter, you can get a more accurate light intensity value

Pin outs:

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

Package Includes :

• 1 x LDR Module Circuit Photoresistor Light Dependent Resistor LDR
