TEMT6000

TEMT6000X01 ambient light sensor is a silicon NPN epitaxial planar phototransistor in a miniature transparent 1206 package for surface mounting. It is sensitive to visible light much like the human eye and has peak sensitivity at 570 nm.

#define LIGHTSENSORPIN A0 //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); 
}
