Light Sensitive Photoresistor LDR Small

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 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: 5000Ω
  • Dark: 20000000Ω

Features

  • It requires less power to operate

What will happen if the photoresistor LDR is exposed to low level light condition?

In the dark, their resistance is very high, sometimes up to 1MΩ, but when the LDR sensor is exposed to light, the resistance drops dramatically, even down to a few ohms, depending on the light intensity. LDRs have a sensitivity that varies with the wavelength of the light applied and are nonlinear devices.
