Analog Output LM393 Optical Photosensitive light sensor module In Pakistan




Product Description

Analog Output LM393 Optical Photosensitive  light sensor module In Pakistan

Arduino photoresistance light sensor module has two output::

1, AO, analog output, real time output voltage signal of sensor.
2, DO, when the light reaches a certain threshold, the output high and low level signal.[The threshold through the potentiometer to adjust].

Arduino photoresistance light sensor module features:

Small size: 33 mm X 14 mm.
Install screw hole is 3 mm.
You can use the 3-5.5 v dc power supply.
Have analog output.
Have turn threshold level output.
Light quality, good linear, high sensitivity.
Has a power light.
The comparator output indicator light.


Using a wide voltage LM393 comparator
With a mouting screw hole, easy to install
Using the sensitive type photosensitive resistance sensor
The comparator output signal clean waveform is good, driving ability, than 15mA
With adjustable potentiometer can adjust the brightness of the light detected
Working voltage: 3.3V-5V
Output: DO digital switch output (0 and 1), AO analog voltage output

This module is sensitive to the light, Usually used for detecting the ambient brightness and light intensity.
When there is no light or the light intensity can not reach the value,DO output is high level.when light intensity over than the value, the module DO output is low level.
The module digital output DO can be directly connected with the microcontroller,use microcontroller detect high or low level, so that can detect the environmental light intensity change.
Can use this board digital output DO port drive relay module directly(our store on sale these relay modules), can also use as a photoelectric switch.
The analog output AO connects with AD module, and it can get more precise light intensity value through the AD converter.

Board Color: Blue
Board Size: Approx 3.2cm x 1.4cm/1.26 x 0.55 inch
