Photosensitive Sensor Module 3Pin 3.3V-5V Photoresistor Light Detection Resistance Module Photo Resistor for Arduino

Photosensitive Sensor Module 3Pin 3.3V-5V Photoresistor Light Detection Resistance Module Photo Resistor for Arduino

Product parameters:

1. Use a wide voltage LM393 comparator

2. Working voltage: DC 3.3～5V

3. The detection angle is around 60 degrees

4. Signal output form: digital switch output (0 or 1)

5. Adopt 5516 sensitive photoresistor

6. The comparator output has a clean signal, good waveform, and strong driving capability, exceeding 15mA

7. Equipped with an adjustable potentiometer to adjust the brightness of the detection light

Applicable environment:

Light brightness detection, light brightness sensor, intelligent car light seeking module

Special attention:

1. Pay attention to wiring according to the diagram and do not make mistakes

2. This document only represents the product parameters at the time of editing. Any changes in the future will not be notified separately

3. The power supply voltage should not exceed 5V, otherwise it may damage the module

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

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

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

7. The DO output terminal can directly drive the relay module, thereby forming a light controlled switch

instructions:

1. Clockwise rotation of the potentiometer can improve module sensitivity, while counterclockwise rotation of the potentiometer can degrade module sensitivity

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.
