ΠΕΡΙΓΡΑΦΗ

A photoresistor (or light-dependent resistor, LDR, or photocell) is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. This module allows for easy sensing of light levels from within your micro controller application. Just connect GND and VCC to the module and a varying voltage depending on light level is available on the third pin. The photosensitive resistances can be divided into three types by their spectral properties: UV resistance, infrared photosensitive resistance, visible light photosensitive resistor.

ΕΠΙΠΛΕΟΝ ΧΑΡΑΚΤΗΡΙΣΤΙΚΑ

This module consists of a photoresistor and a 10  in-line resistor. The photoresistor's resistance will decrease in the presence of light and increase in the absence of it. The output is analog and determines the intensity of light.

  • Operating Voltage: 3.3V to 5V
  • Output type: Analog


ΔΥΝΑΤΟΤΗΤΕΣ

  • Dark Current, Dark Resistance: Photosensitive resistance at a certain applied voltage, when the light is not irradiated, the flowing Current is called Dark current. Applied voltage and Dark current ratio is the Dark Resistance;
  • Sensitivity: Sensitivity is irradiated by light sensitive resistor, the resistance value (dark resistance) when irradiated with light Resistance value (light resistance) the relative change in values.
  • Volt-ampere characteristic curve. Voltage characteristic curves are used to describe the resistance of the applied voltage and the photosensitive photocurrent relationship, On the photosensitive devices, the light current with applied voltage increases.
  • Temperature coefficient. At a low temperature photoelectric Sensitivity is high and vice versa. 
  • Rated power. Photosensitive resistor rated power is allowed for certain lines. when the temperature rise High, its power consumption is reduced.
