This component is known as LDR or Light Dependent Resistor. LDR can sense light intensity and changes its resistance depending on light. Normally the resistance of LDR is high but when light falls over on it the resistance decreases automatically.
- Can be used to sense Light
- Easy to use on Breadboard or Perf Board
- Easy to use with Microcontrollers or even with normal Digital/Analog IC
- Small, cheap and easily available
- Dimension: 5mm
