1. Use a wide voltage LM393 comparator<\/p>\n

2. Working voltage: DC 3.3\uff5e5V<\/p>\n

3. The detection angle is around 60 degrees<\/p>\n

4. Signal output form: digital switch output (0 or 1)<\/p>\n

5. Adopt 5516 sensitive photoresistor<\/p>\n

6. The comparator output has a clean signal, good waveform, and strong driving capability, exceeding 15mA<\/p>\n

7. Equipped with an adjustable potentiometer to adjust the brightness of the detection light<\/p>\n

<\/p>\n

Applicable environment:<\/p>\n

Light brightness detection, light brightness sensor, intelligent car light seeking module<\/p>\n

<\/p>\n

Special attention:<\/p>\n

1. Pay attention to wiring according to the diagram and do not make mistakes<\/p>\n

2. This document only represents the product parameters at the time of editing. Any changes in the future will not be notified separately<\/p>\n

3. The power supply voltage should not exceed 5V, otherwise it may damage the module<\/p>\n

4. The photoresistor module is most sensitive to ambient light and is generally used to detect the brightness of surrounding light, triggering microcontrollers or relay modules, etc<\/p>\n

When the ambient light brightness does not reach the set threshold, the DO terminal outputs a high level. When the ambient light brightness exceeds the set threshold, the DO terminal outputs a low level<\/p>\n

6. The DO output terminal can be directly connected to the microcontroller to detect high and low levels, thereby detecting changes in ambient light brightness<\/p>\n

7. The DO output terminal can directly drive the relay module, thereby forming a light controlled switch<\/p>\n

<\/p>\n

instructions:<\/p>\n

1. Clockwise rotation of the potentiometer can improve module sensitivity, while counterclockwise rotation of the potentiometer can degrade module sensitivity<\/p>\n

When the light intensity is below the module’s sensitivity threshold, the sensitivity indicator light will turn off and the signal port will output a high level; When the light intensity is higher than the module’s sensitivity threshold, the sensitivity indicator light will turn on and the signal port will output a low level.<\/p>\n
