APPLICATIONS
Ambient light sensor for control of display backlight dimming in LCD displays and keypad backlighting of mobile devices and in industrial on/off-lighting operation.
• Automotive sensors
• Mobile phones
• Notebook computers
• PDA’s
• Cameras
• Dashboards
Connection
Code
[codesyntax lang=”cpp”]
#define LIGHTSENSORPIN A1 //Ambient light sensor reading
void setup()
{
pinMode(LIGHTSENSORPIN, INPUT);
Serial.begin(9600);
}
void loop()
{
float reading = analogRead(LIGHTSENSORPIN); //Read light level
float square_ratio = reading / 1023.0; //Get percent of maximum value (1023)
square_ratio = pow(square_ratio, 2.0);
Serial.println(reading);
delay(1000);
}
