5mm LDR Light Dependent Resistor Photoresistor - 10Pcs

The LDR 5mm Light Dependent Resistor PhotoResistor sensor is a versatile component used in various light-sensing applications. Also known as a photoresistor or cadmium sulfide (CdS) cell, it operates based on the principle of photoconductivity, where its resistance decreases with increasing light intensity. Here's a breakdown of its features and applications:

  Features:  

• Diameter: 5 mm
• Number of Pins: 2
• Dark resistance: 1-20M ohm

  Analog Applications:  

1. Camera exposure control
2. Auto slide focus (dual cell)
3. Photocopy machines (toner density control)
4. Colorimetric test equipment
5. Densitometer
6. Electronics scales (dual cell)
7. Automated rear-view mirror

  Digital Applications:  

1. Automatic headlight dimmer
2. Nightlight control
3. Oil burner flame-out detection
4. Streetlight control
5. Absence/presence detection (beam breaker)
6. Position sensor
