What is LDR Sensor | #sensors

The LDR stands for Light Dependent Resistor. This means the resistance across the LDR is get's decreases when the light intensity gets increases and vice-versa. Mainly this sensor is used to detect the light & light intensity. The output of this module gets high when resistance across LDR gets Low & Vice-Versa. The output signal can be controlled by the onboard potentiometer on the module. This sensor is compatible with Arduino, We can simply interface this sensor to the Arduino & we can build major projects using this module. Basically, this sensor is used in the automatic light control system, Automatic Street light system.

Pinouts:-

• It can detect light intensity.

• Output can be adjusted using Potentiometer.

• This sensor works on 3.3V to 5V DC Supply.

• Compact PCB Design:- 3cm X 1.6cm

• IC Used LM393
