Light Intensity Detection Sensor Photoresistor Module 3-Pin for Arduino UNO

Great Sensors for Arduino Project. Having Fun With Electronics and Programming!

Description:

1. The Light Intensity Sensor can be used for brightness and the ambient light intensity detection, which is widely used in intelligent car.
2. Compared with photo-resistor, photoresistor is better in directionality. It only detect light source in front of the sensor. It is better to use for light searching.
3. "DO" outputs 0 and 1 digital signal.
4. When ambient light intensity does not reach the threshold value, the "DO" port output high lever; When the ambient light intensity exceeds a set threshold, the "DO" output low lever.
5. Digital outputs "DO" can be directly connected with the microcontroller.
6. Sensitivity is adjustable by adjusting the potentiometer.
7. PCB-mounted LEDs indicate the power (Red) and digital switch output (Green).
