4 Pin LM393 Optical Sensitive Resistance Light Detection Photosensitive Sensor Module
โมดูลใช้ในการตรวจจับความสว่างและความเข้มของแสง LM393 Optical Sensitive Resistance Light Detection Photosensitive Sensor Module
โมดูลนี้ให้สัญญาณออกมาเป็นแบบดิจิตอล คือ 0 กับ 1 และ อนาล็อก สามารถปรับตัวต้านทานปรับค่าได้ ว่าจะให้สว่างเท่าใดจึงจะส่งค่าเอาต์พุตออกมา ได้ตามต้องการ

– LM393 Optical Sensitive Resistance Light Detection Photosensitive Sensor Module แบบ 4 ขาUses:
– light brightness detection, light brightness sensor, smart car light seeking moduleModule features: 1, using sensitive
photoresistor sensor2, comparator output, clean signal, good waveform, strong driving ability, more than 15mA. 3,
with adjustable potentiometer can adjust the detection light brightness4, working voltage 3.3V-5V5, output form: DO
digital switch output (0 and 1) and AO analog voltage output6, with fixed bolt holes, easy to install7, small board PCB
size: 3.2cm x 1.4cm8, using wide voltage LM393 comparator
– module instructions1, photosensitive resistor module is most sensitive to ambient light, generally used to detect the
brightness of the surrounding environment, trigger microcontroller or relay module and the like;2, when the ambient
light level module reach the set threshold value, the DO output high, when the ambient light level exceeds a set
threshold value, the DO terminal output low;3, may be associated with the DO output of the microcontroller Directly
connected, through the MCU to detect high and low level, thereby detecting the change of the light brightness of the
environment;4, DO output can directly drive the store relay module, which can form a light control switch.5, the small
board analog output AO can be connected with the AD module, through the AD conversion, you can get more
accurate values ​​of ambient light intensity;Product wiring instructions:1, VCCconnected to the power supply positive
3.3-5V2, GND connected to the negative power supply3, DOTTL switch signal output4. AO analog voltage output
