Hookup Guide
SEPTEMBER 20, 2018
The Melexis MLX90640 contains
a 32x24 array of thermopile
sensors creating, in essence, a
low resolution thermal imaging
camera. In this guide, we’ll go
over how to connect your Qwiic
Infrared Array with MLX90640
and get it communicating with
Processing to produce a nice
thermal image.

I am curious about the stated low end of the IR detection range of -40°C. How cold must the array be to
achieve this?

Hi, can this work with Raspberry pi

Hi, I recently bought this sensor. I am using an Arduino Due and the source code provided for “Basic
Readings”, but there seems to be an issue during the parsing of EEPROM information. The function
MLX90640_ExtractParameters() returns -4. I traced this error code to the function ExtractDeviatingPixels():
which returns a -4 because of the following statement:
else if(outlierPixCnt > 4)
This seems to cause all of the values to be NaN (I’m assuming there is a divide by zero somewhere). Any
suggestions?

I look at the I2C buss traffic with a logic analyzer, and notice that Arduino is requesting data in 32 byte
chunks (starting at 0x2400). However, every 32 bytes of received data are identical to the first 32-bytes…
something is not right

Note that as with the black board, the orientation of the device, and hence the “image”, is not square with any
edge of the board. See tab.

The temperature measurement range is incorrect. -40 to 85°C is the operational temperature range. The
sensor can measure object temperature between -40 to 300°C.

In 2003, CU student Nate Seidle fried a power supply in his dorm room
and, in lieu of a way to order easy replacements, decided to start his
own company. Since then, SparkFun has been committed to sustainably
helping our world achieve electronics literacy from our headquarters in
Boulder, Colorado.
No matter your vision, SparkFun's products and resources are designed
