LM393-based design.
Sensitivity adjustable (potentiometer adjustment).
Operating voltage: 3.3V to 5V DC.
Operating current: 15mA.
Module pin 3 pins.
The output type is digital output (D0).
LDR Module is also called a Light Sensor. LDR (Light Dependent Resistor) means Resistance based on light, thus it is a type of resistance that depends on light. Its resistance is inversely proportional to light, if light increases then its resistance decreases and if light decreases then its resistance increases. It is a 4 pin module that can efficiently detect ambient brightness and light intensity
