Could you attach the code you are using? Also how are you connecting your sensor, have you already seen this datasheet http://www.melexis.com/Assets/IR-sensor-thermometer-MLX90614-Datasheet-5152.aspx ? Are you using a breakout board or an Arduino expansion board?
I'm using the following code : adafruit/Adafruit-MLX90614-Library · GitHub
And this sheme : https://skyduino.files.wordpress.com/2013/11/s0172017.jpg
And my edison is plugged into an arduino expansion board
I saw the datasheet, but ... well, i do have some difficulties to decrypt everything it says ^^'
When you ran the code from https://github.com/adafruit/Adafruit-MLX90614-Library what error do you get? Does it compile and does nothing or do you get any specific error? Do you have the Adafruit_MLX90614 library folder your /libraries/ folder? I downloaded the library and it compiled fine in the IDE however I don’t have that specific sensor to test it.
It compiles when I upload the code, but I simply don't have the good output.
The output is the same as if there was no sensor, it doesn't detect it or the i²c bus doesn't work
