The LDR sensor is made of Semiconductor materials with high Resistance like Silicon or Germanium. It is a light-sensitive device, so this resistor has a different resistance value day and night as given below:
-
- Daylight: 5000Ω
- Dark: 20000000Ω
Features
- It requires less power to operate
- Quick Response
- Easy to use
- Generate high current
