MLX90614 Series 5.5 V 13.5 mA Gradient Compensated Infra Red Thermometer - TO-39

Hello community,

this is my very first post so I will try to be as accurate and detailed as can be.

I am in the US
I have a thermal sensor MLX90614 and I have an Arduino Due which runs at 3v. Unfortunately the sensor runs at 5v.
The reason I ask is that this project is for a thermal imaging camera, V1 used Arduino Uno but it took 6minutes to generate a picture. I am using the Due because of the M3 processors which will cut the time down substantially.

Can I power this sensor using the 5v from the board or do I have to buy a different Arduino board?

thank you very much!

Gabriel

You could use a "boost" 3V to 5V converter to power the sensor you have, but then you would need bidirectional level shifters for the input/output pins. Save yourself a lot of trouble and buy the 3.3 V version of the MLX90614. Sparkfun has them.

perfect! I will buy it from Sparkfun thank you sir!

If you are using image deconvolution to sharpen the IR maps, I think there would be a lot of interest in your results. Please post what you are up to!
