Hi There,
I have been trying to get this IR temperature sensor working with standard code offered by Adafruit but no luck.
It keeps sending out an incorrect "fixed temperature" reading as shown below and not response any object in front the sensor.
I don't know what go wrong and hope someone can help me out here. Thanks,
I am using Arduino UNO board with exact setting same as Adafruit's Tutorial.
No tweaking or changing.
Here is the result/
Adafruit MLX90614 test
Ambient = 1037.55*C Object = 1037.55*C
Ambient = 1899.59*F Object = 1899.59*F
Ambient = 1037.55*C Object = 1037.55*C
Ambient = 1899.59*F Object = 1899.59*F
Ambient = 1037.55*C Object = 1037.55*C
Ambient = 1899.59*F Object = 1899.59*F
Ambient = 1037.55*C Object = 1037.55*C
Ambient = 1899.59*F Object = 1899.59*F
Ambient = 1037.55*C Object = 1037.55*C

Post a photo of your hardware and we'll see if that tells us anything. The photo you posted is from the tutorial, and we know that one works.

The wiring looks good.
Double check the voltages at the sensor's pins to make sure the power is really getting where it needs to go, and try a different set of jumper wires for the I2C connections.

Hello Mike,
You are my savior, it is indeed a faulty "jumper wires" that connected to I2C.
My apology, I should have double checked on that before making this post.
Anyway, thank you for such big help.

Glad to hear you got things working.
Don't worry about being caught by the bad jumper. It takes a certain amount of expeience debugging hardware to develop the paranoid distrust of absolutely everything necessary to avoid surprises like that.
