‫ TEMT6000 Light Meter Program ‫
‫ ‫
‫ Simple program to read the analog output of the TEMT6000 and display ‫
‫ the raw reading, voltage and the calculated Lux ‫
‫ ‫
‫ We are connecting sensor to analog input A0, but this can be any analog pin. ‫
‫*/ ‫

‫int const TEMP6000_PIN = A0; ‫
‫int const AREF = 5.0; // set for 5.0 or 3.3 depending on voltage of uC ‫

‫void setup() { ‫
‫ Serial.begin(9600); // Initialize serial comm ‫
‫} ‫
‫//=============================================================================== ‫
‫// Main ‫
‫//=============================================================================== ‫
‫void loop() { ‫
‫ ‫
‫// The math is broken out into steps to make it easier to follow. ‫
‫float sensor_value = analogRead(TEMP6000_PIN); // Get raw sensor reading ‫
‫float volts = sensor_value * AREF / 1024.0; // Convert reading to voltage ‫
‫float amps = volts / 10000.0; // Convert to amps across 10K resistor ‫
‫float microamps = amps * 1000000.0; // Convert amps to microamps ‫
‫float lux = microamps * 2.0; // 2 microamps = 1 lux ‫
‫ ‫
‫// All the math above can also be replaced with the following formula ‫
‫// assuming AREF is 5.0 volts. ‫
‫ ‫
‫ // float lux = sensor_value * 0.9765625; ‫

‫Serial.print ("Raw ADC data: "); ‫

‫Serial.print (volts); ‫
‫Serial.print (" Lux: "); ‫
‫Serial.println (lux); ‫
