Infrared Non-contact Thermometer (Qwiic) - MLX90632

Have you ever used one of those noncontact temp guns? This is the newest and smallest version that sensor. Point the MLX90632 at an object and remotely get its temperature within 1 degree C. This is a fun little sensor to play with!

The MLX90632 is basically MLX90614 that we currently sell but in the smaller and easier to use SMD package. The MLX90632 has a shocking resolution of 0.02C from -20 to 85C, a very low supply current of 1mA, and a field of view of 50 degrees. Default read rate is 0.5s per measurement.

The SparkX carrier board has a jumper to control the I2C address, remove the pull up resistors if needed, and two Qwiic connectors to get you up and running very quickly.

The formulas to get this device to work are complex and require 64-bit operations. We've got a library available here that is available through the Arduino library manager as well. Search for 'SparkFun MLX90632'.

We do not plan to regularly produce SparkX products so get them while they’re hot!

NOTE: The I2C address of the MLX90632 is 0x3B and is jumper selectable to 0x3A. A multiplexer/Mux is required to communicate to multiple MLX90632 sensors on a single bus. If you need to use more than one MLX90632 sensor consider using the Qwiic Mux Breakout.

Experimental Product: SparkX products are rapidly produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.

    Don't know if you guys are looking for feedback on these SparkX products, or if you're just having a bit of fun, but I like this chip. I don't think there are any small, SMD IR temperature sensors that replace the likes of the TMP006 that don't need a thermal relief area on the PCB, so this is a really nice replacement. Just FYI.

Well it works...

Works fine but the assembly looks like hell. I think your pick and place needs to be 'indicated in' and your solder looks like part dirt. There's a soldered jumper with so big a blob I could assemble another board with the amount. I don't know about you guys but I want my stuff to look as pretty on the outside as pretty as I want it to work
