For this sketch you need to connect:
VCC to 3.3V or 5V and GND to GND of arduino
SDA to A4 and SCL to A5


#include <LM75A.h>

// Create I2C LM75A instance
LM75A lm75a_sensor(false,  //A0 LM75A pin state
                   false,  //A1 LM75A pin state
                   false); //A2 LM75A pin state
// Equivalent to "LM75A lm75a_sensor;"

void setup(void)
  Serial.println("Robojax LM75A Test");
  Serial.println("Temperatures will be displayed every second:");

void loop()
  // Robojax.com LM75A Test
  float temperature_in_degrees = lm75a_sensor.getTemperatureInDegrees();

  if (temperature_in_degrees == INVALID_LM75A_TEMPERATURE) {
    Serial.println("Error while getting temperature");
  } else {
    Serial.print("Temperature: ");
    Serial.print(" degrees (");
    Serial.println(" fahrenheit)");
