$3.99

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
}
