LDR Light Intensity Sensor Module

The photosensitive resistor module most sensitive to ambient light, generally used to detect the brightness of the ambient light, triggering microcontroller or relay modules;

The module brightness of ambient light reach the set threshold, DO-side output high when the ambient light level exceeds the set threshold, DO-ended output low;

DO output can be directly connected with the microcontroller through the microcontroller to detect high and low, thereby detecting changes in ambient light intensity;

DO OUR outputs can directly drive the relay module, which can be composed of a light control switch.Speed range of 0% to 100%

Feature:

• Using the sensitive type photosensitive resistance sensor
• The comparator output signal clean waveform is good, driving ability, than 15mA.
• With adjustable potentiometer can adjust the brightness of the light detected
• Working voltage 3.3V-5V
• The output format: Digital switching output (0 and 1)
• With bolt holes for easy installation
• A small board PCB size: (L*W)3.20 x 1.40cm/1.26"*0.55"
• Using a wide voltage LM393 comparator

Product connection details:

• VCC connect the power positive 3.3-5 v
• GND connect power cathode
