The code above is to show whether the OLED is communicating with Arduino. If you are having trouble with this address, us I2C scanner to get the OLED address. Absolute Maximum Rating for MLX90614, extracted from Melexis, Datasheet for MLX90614 , page 7 As can see from the "BAA" model, the safe supply voltage is around 3. #ifndef USE_MLX90614 #define USE_MLX90614 // [I2cDriver32] Enable MLX90614 ir temp sensor (I2C address 0x5a) (+0. SCL is the I2C clock pin, connect to your Arduino's I2C clock line. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can.
