Beschreibung

• Features: The brightness of surrounding surroundings and the sunshine intensity could be detected (compare with the photoresistor, directivity is comparatively good, can perceive the fixed course of the light source)Sensitivity adjustable the blue digital potentiometer adjustment (Figure)Operating Voltage: three switching outputs (0 and 1)With fixed bolt hole for easy installationSmall board PCB Size: Approx 3 * 1 / 1" * 0" Usage: Light point detection, the brightness of the sunshine sensor is directional, solely inductive sensor in entrance of the sunshine source used find light greater Instructions: Photodiode module is maximum touchy to the ambient light, generally used to stumble on the brightness of the ambient light intensity, photoresistor sensor module Universal In most cases, the adaptation between the two is that photodiode module directional, can sense the constant the path of the light source in the mild situations or the light intensity of lower than a set threshold, DO port outputs a excessive level, when the external environment when the sunshine intensity exceeds the set threshold value, the module D0 output is low small board digital output D0 would be connected immediately with the microcontroller microcontroller to detect high and occasional to locate environmental mild intensity substitute board digital output DO OUR relay module can immediately drive, which can be composed of a photoelectric switch Package Included: 1pcs x 4PIN LM393 Light Sensor Switch Module Digital Photosensitive Diode Detection Switch Board Photodiode Module for Arduino
