Light Sensitive Photoresistor LDR
LDR Stands for Light Dependent Resistor and its Resistivity varies with Incident Electromagnetic Radiations so, its resistivity is a function of Incident Electromagnetic Radiations or light. Other names of LDR are photoresistor, Photoconductor, Photocell, and photo-conducting cell

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
Read our blog on LDR Sensor detailing what is LDR, the working principle of LDR, Variations in resistance to change in light intensity, types, advantages, disadvantages, and applications of LDR sensors.
Application
- Camera Exposure Control
- Auto Slide Focus
- Photocopy Machines
- Colorimetric Test Equipment
- Densitometer
Also check LDR 5mm Metal Housing (Pack of 5) available on the Robocraze website. The Light Dependent Resistor (LDR) is a semiconductor device made of materials like Silicon or Germanium. Its resistivity varies with incident electromagnetic radiations or light, with resistance values of 5000Ω in daylight and 20000000Ω in the dark. The product features quick response, low power consumption, and high current generation. It is commonly used in applications such as camera exposure control, auto slide focus, photocopy machines, colorimetric test equipment, and densitometers.
