Description
Uses:
Light level detection, the brightness of the light sensor is
directional, only inductive sensor in front of the light source used to
find light better
Module Features:
1. The brightness of surrounding environment and the light
intensity can be detected (compare with the photoresistor, directivity
is relatively good, can perceive the fixed direction of the light
source)
2.Sensitivity adjustable the blue digital potentiometer adjustment (Figure)
3. Operating voltage 3.3V-5V
4. Digital switching outputs (0 and 1)
5. With fixed bolt hole for easy installation
6. Small board PCB size: 3.2cm * 1.4cm
Instructions for use
1. Photodiode module is most sensitive to the ambient light,
generally used to detect the brightness of the ambient light intensity,
photoresistor sensor module Universal In most cases, the difference
between the two is that photodiode module directional, can sense the
fixed the direction of the light source.
2. Module in the light conditions or the light intensity of less
than a set threshold, DO port outputs a high level, when the external
environment when the light intensity exceeds the set threshold value,
the module D0 output is low;
3. The small board digital output D0 can be connected directly with
the microcontroller microcontroller to detect high and low to detect
environmental light intensity change;
4. Small board digital output DO OUR relay module can directly drive, which can be composed of a photoelectric switch;
Package Include:
1pcs LM393 light Sensor Module 3.3-5V input light Sensor for Raspberry pi Arduino
