Light Sensor Module

Features:

• Digital Light Sensor Module
• Adjustable threshold via onboard potentiometer
• Pinout:
• VCC: Power
• GND: Ground
• DO: Digital Output (High when threshold is passed)
• When it is dark, the sensor outputs High, When it is light, the output is low.
• Operating Voltage: 3.3V-5V
• Current Rating: 15mA
• Arduino and Raspberry Pi Compatible

Sample code for Arduino:

/*
Connection:
Sensor DO => Arduino D7
VCC => Arduino 5V
GND => Arduino GND

Adjust the screw on the potentiometer clockwise or counterclockwise to change
the light threshold that triggers the sensor
*/

int ledPin = 13; // LED connected to digital pin 13 
int inPin = 7; // Sensor Output connected to digital pin 7 
int val = 0; // variable to store the read value 

void setup() { 
pinMode(ledPin, OUTPUT); // sets the digital pin 13 as output 
pinMode(inPin, INPUT); // sets the digital pin 7 as input 
} 

void loop() { 
val = digitalRead(inPin); // read the input pin 
digitalWrite(ledPin, val); // sets the LED on Arduino to the sensor's value 
}
