Description

3.3V-5V 3PIN LM393 Light Sensor Switch Module Digital Photosensitive Diode Detection Switch Board Photodiode Module

describe:

100% brand new and high quality

 

usage:

Light level detection, the brightness of the light sensor is directional, it is better to only detect the light in front of the light source used by the sensor

 

Module features:

1. It can detect the brightness of the surrounding environment and the light intensity (compared with photosensitive, the directivity is better, and the fixed direction of the light source can be sensed)

2. Sensitivity adjustable blue digital potentiometer adjustment (picture)

3. Working voltage 3.3V-5V

4. Easy to install fixing bolt holes

5. Small board PCB size: 3.2cm*1.4cm/1.25″*0.55″

 

Instructions for use:

1. The photodiode module is the most sensitive of the ambient light, usually used to detect the brightness of the ambient light intensity, the photosensitive sensor module is common in most cases, the difference between the two is that the orientation of the photodiode module can be sensed Fixed direction light source

2. When the module is under light conditions or the light intensity is lower than the set threshold, when the DO port outputs high level, when the light intensity exceeds the set threshold in the external environment, the output of the module D0 is low

3. The digital output D0 of the small and medium-sized board can be directly connected to the single-chip micro-controller to detect high and low, and detect changes in ambient light intensity

4. The digital output of the small and medium board can be directly driven by the relay module, which can be driven by a photoelectric switch

Package Included:

1 light sensor module
