light intensity, light intensity sensors, directional, only the inductive sensor in front of the light source for the light to find
1 can detect the brightness and intensity of the ambient light?Compared with photosensitive resistance, directionality, can sense the direction of the light source fixed?
2 adjustable sensitivity?The blue digital potentiometer adjustment?
3 Operating Voltage 3.3V-5V
4 Output form: DO digital switching output?0 and 1?And AO analog voltage output
5 has a fixed bolt hole for easy installation
6 small PCB board size: 3.2cm * 1.4cm
Instructions for use
1 photodiode module ambient light intensity of the most sensitive, generally used to detect ambient brightness and intensity, can be common with the sensor module photoresistor In most cases, the difference between the two is that the photodiode module direction, can perceive a light source fixed direction.
2 module in conditions without light or light intensity not reach the threshold value, DO port output high, when the ambient light intensity exceeds the set threshold, the module D0 output low;
3 small board digital output D0 can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the light intensity changes in the environment;
4 small board digital output DO OUR relay module can directly drive, which can be composed of a photoelectric switch ;
5 small plates analog output AO can shop AD module is connected, by the AD converter, you can get a more accurate ambient light intensity value
