3.3-5V Input LM393 Light Sensor Module for Arduino DO/AO Output Dupont Cables CF
$ 5.50
DESCRIPTION
That can sense the fixed direction of the light source can detect the brightness of surrounding environment and the light intensity (comparison with the photoresistor, directional comparison)
Sensitivity adjustable the blue digital potentiometer adjustment (Figure)
Operating voltage 3.3V-5V
PCB size: 3cm * 1.6cm
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.Module digital output D0 can be directly connected with the microcontroller, microcontroller to detect high and low, to detect environmental light intensity change; 4.Module digital output DO module can directly drive relays, which can form a photoelectric switch
5.Module analog output AO and AD module connected through the AD converter, the ambient light intensity can get more precise values
