Description: 1Pcs Sensor Module Photoresistance Detection Optical Photosensitive Light Ic New Item Description: Comparator chip LM393.it is stable. Can detect the ambient brightness and light intensity. Accuracy adjustable. Operating voltage 3.3V-5V. Output: DO digital switch outputs (0 and 1) AO analog voltage output. power indicator and digital switch output indicator. With a mounting screw hole. PCB size: 3.1cm * 1.5cm. Interface Description (4-wire). 1 VCC -- 3.3V-5V voltage. 2 GND -- GND. 3 DO -- board digital output interface (0 and 1). 4 AO -- board analog output interface. Introduction. 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 use as a photoelectric switch. The analog output AO connect with AD module,it can get more precise light intensity value through the AD converter.
