3Pin LDR Module – Optical Sensitive Resistance Light Detection Sensor Module

3pin LDR Module – Optical Sensitive Resistance Light Detection Sensor Module

• Using the sensitive type photoresistor sensor
• The comparator outputs a signal clean, good waveform driving ability more than 15mA.
• With adjustable potentiometer can adjust the light intensity detected
• The working voltage: 3.3V-5V
• The output format: Digital switching output (0 and 1)
• With a fixed bolt holes for easy installation
• Small PCB board size: 3.2cm x 1.4cm
• Using a wide working voltage range LM393 comparator
• Application: Light intensity is detected, the light intensity sensor, smart car search light module

?Features:?

• Photosensitive resistor module most sensitive to environmental light, generally used to detect the brightness of ambient light, triggering microcontroller or relay module;
• When ambient light intensity does not reach the threshold value, the module DO-side output high when the ambient light level exceeds the set threshold, DO terminal output low;
• DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the brightness of ambient light changes;
• DO output can directly drive the relay module, which can be composed of a light control switch.

Pin Configuration:?

• VCC for positive power supply 3.3-5V
• GND for power supply is negative
• DO TTL switching signal output
