TEMT6000 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.
Features
• Adapted to human eye responsivity
• Wide angle of half sensitivity ϕ = ± 60°
Applications
Ambient light sensor for display backlight dimming in:
Mobile phones
Notebook computers
PDA’s
Cameras
Dashboards
Connection and Layout
| TEMT6000 Pin | Chipkit Uno Pin |
| SIG | A0 |
| GND | GND |
| VCC | 3v3 |
Code
No libraries needed
[codesyntax lang=”cpp”]
#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);
}
