LDR 5mm Metal Housing
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.
LDR sensor 5mm – Metal Housing is a resistor which made of semi-conductor material, and the conductance changes with luminance variation .The photoresistor can be manufactured with different figures and illuminated area based on this characteristic. Photoresistor is widely used in many industries, such as toys, lamps, camera, etc.
LDR 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 in day and night as given below:
- Daylight: 5000?
- Dark: 20000000?
Also, read our blog Uses of LDR detailing every related LDR Sensor from the definition, and working principle, to the uses of LDR sensors in a variety of projects.
