This is a photosensitive sensor module/light module��that detects the photosensitive resistor for Arduino. The photoresistor module detects light intensity. As the intensity of light on the photoresistor increases, so does the resistance of the photoresistor decreases.
A built-in 10k resistor on the��Digital Light Sensor module��can be used to build a divider circuit for measuring changes in light intensity from the photoresistor. A device such as an Arduino can be used to read the light intensity using an analog input pin.
The most sensitive to ambient��light photosensitive resistance module,��commonly used to detect the environment around the brightness of light, or MCU trigger relay module, etc.��The��LDR Light Sensor Module��in the ambient light intensity than the set threshold, DO high-level output, when the ambient ligset threshold, the DO output low level
- Using a sensitive photoresistor sensor.��
- Comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15 mA.��
-
With an adjustable potentiometer, you can adjust the brightness of the detection light.��Operating voltage: 3.3V-5V. Output form: digital switch output (0 and 1).��
- With fixed holes for easy installation.��
- Higher sensitivity, whereas the sensitivity at high temperatures, is lower.

Additional Details
- The photosensitive device, its photocurrent increases with the applied voltage.
- the temperature coefficient. Photoelectric effect photoresistor influenced by temperature, partial photoresistor optoelectronic at low temperatures
- rated power. Refers to the rated power for a certain line photoresistor allowed power consumed when the temperature rises.
- High, its power consumption is reduced.
- According to the spectral characteristics of the photoresistor has three photoresistors: Ultraviolet photosensitive resistance, infrared light-sensitive resistors, Visible photosensitive resistance.
