Hello friends
Today in this video I am going to show you what is LDR and how to use it. Full name of LDR is Light Dependent Resistor or Photoresistor, it is a resistance which changes according to light intensity.

Resistance of LDR is very high in dark and it become low in light, in other words we can say LDR is a sensor which is used for Light Intensity Measurement.

we can use LDR in many electronics circuit Like
1. Smart Street Light
2. Fire Alarm
3. Pulse Rate Sensor
4. Security System
