  • Spectral characteristics: UV light-sensitive resistors, infrared light-sensitive resistors, visible photoresistor

  • Dark current and dark resistance: Current flowing in the photoresistor without light irradiation, ratio of applied voltage to dark current is dark resistance

  • Sensitivity: Relative change in resistance from dark resistance to light resistance when exposed to light

  • Voltage characteristic curve: Describes the relationship between applied voltage and photocurrent of the photoresistor

  • Temperature coefficient: Influence of temperature on the sensitivity of the photoresistor, higher sensitivity at low temperatures, lower sensitivity at high temperatures

  • Rated power: Maximum power consumption allowed for a specific photoresistor, reduced with high temperature rise.

The KY-018 Photosensitive Resistor Sensor Module is designed to detect and measure light intensity. It features various spectral characteristics, including sensitivity to UV light, infrared light, and visible light. The module incorporates a photosensitive resistor that exhibits changes in resistance in response to different levels of light. The module provides information on dark current and dark resistance. Dark current refers to the current flowing through the photoresistor when it is not exposed to any light. Dark resistance is the ratio of the applied voltage to the dark current. These parameters help characterize the behavior of the photoresistor in the absence of light. The sensitivity of the photoresistor is another important aspect. It measures the relative change in resistance from the dark resistance to the light resistance when the photoresistor is exposed to light. This sensitivity value indicates how responsive the photoresistor is to changes in light intensity. The voltage characteristic curve describes the relationship between the applied voltage and the photocurrent of the photoresistor. This curve provides insights into how the photoresistor's electrical properties vary with different voltage levels. The temperature coefficient is an important consideration as well. It represents the influence of temperature on the sensitivity of the photoresistor. Typically, the sensitivity of the photoresistor is higher at lower temperatures and lower at higher temperatures. The rated power specification indicates the maximum power consumption allowed for the specific photoresistor. It takes into account the temperature rise that can occur during operation, with reduced power consumption at higher temperatures to prevent overheating. The KY-018 Photosensitive Resistor Sensor Module offers a convenient and reliable solution for measuring light intensity and detecting changes in ambient light conditions. It is widely used in applications such as automatic light control systems, photography, and other projects requiring light sensing capabilities.
