TEMT6000 Ambient Light Sensor

Product Description:

    Basic breakout board for the TEMT6000 Ambient Light Sensor. Only what you need, nothing you don't. Sensor acts like a transistor - the greater the incoming light, the higher the analog voltage on the signal pin.

Technical Specifications:

• Collector emitter voltage: 6V;
• Collector emitter voltage: 1.5V;
• Maximum current: 20mA;
• Power supply module: 3.3V - 5V;
• Wavelength: 570nm;
• Detection angle: 60 ^o .
• Dimensions: 14 x 8 mm.
• Phototransistor datasheet : link

Pinout:

Connection Example:

For this example you'll need:

1 x TEMT6000 Ambient Light Sensor | Reference: BZJVJR_TEMT6000
1 x Development board UNO R3 Arduino compatible | Reference: TXVMOK_DB-UNO-R3 
  wires for electrical connections

Code example:

#define LIGHT_SENSOR A0 // define input pin

void setup() {
Serial.begin(9600);
}

void loop() {
int Lvalue = analogRead(LIGHT_SENSOR);// read the light
int mVolt = map(Lvalue,0, 1023, 0, 5000);// map analogue reading to 5000mV
int percent = map(Lvalue,0, 1023, 0, 100);// map analogue reading to 100%
float volt =(double)mVolt/1000;// convert millivolt to volt

Serial.print(mVolt);// print millivolt
Serial.print( "mV ...... ");
Serial.print(volt,3);// print volts with 3 decimal places
Serial.print( "V ...... ");
Serial.print(percent);// print percentage
Serial.println( "%");
delay(1000);// wait for 1000 milliseconds
}

   The signal on A0 pin is transformed into values in Serial Monitor relatively to 5V from VCC.
