Photodiode Sensor Module Photodioda

Photodiode Sensor Module

Uses:
Light intensity detected light intensity sensor , directional , just in front of the light -sensitive sensor for better search light

Module Features :

• can detect the brightness and the ambient light intensity ( compared with photoresistor better directionality , the light source can     sense a fixed direction )
• adjustable sensitivity ( shown in blue digital potentiometer adjustment )
• Operating voltage 3.3V-5V
• Output format : DO digital switching outputs ( 0 and 1 ) and AO analog voltage output
• has a fixed bolt holes for easy installation
• PCB Size : 3.2cm * 1.4cm

Instructions for use:

• photodiode module most sensitive to environmental light intensity , generally used to detect the ambient brightness and light intensity , can be common with photosensitive resistance sensor module in most cases , the difference between the two is that a better directional photodiode module , you can sensing light in a fixed direction .
• module dull conditions or when the light intensity of less than the set threshold , DO port output high when the ambient light intensity exceeds a set threshold, the module output low in D0 ;
• digital outputs D0 can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting the light intensity changes in the environment ;
• 4.digital outputs can directly drive DO OUR relay module , which can be composed of a photoelectric switch ;
• 5.AO analog output modules can be connected and shop AD through the AD converter , you can get a more accurate light intensity values ;
