Temp sensor for sparki

Sparki
#1

Hi. I am thinking of getting my sparki to take temp measurements around the house. Most Arduino sensors I am familiar with are of the analog variety - am I correct to assume that they wouldn’t work with sparki ? Or is there a way to have analog inputs?

If the only way is for digital instrumentation, any suggestions?

Thanks

From what I’m reading, the atmega32u4 board (the one used in Sparki) actually has an onboard temperature sensor. It senses the temperature inside the chip, so this may not be what you’re looking for:

For an external sensor, this little guy might work:

Here is a list of digital temp sensors:

Hi nchio,

Sparki has an expansion port on the side that you can use as regular arduino pins. Analog pins are included amongst these:

Thank you cvpsmith, will give it a try.

Hi roboalchemist, I did notice the port but the lack of a clear label (eg A1, A2,… - apologies am a noob) threw me off.

Just to be certain, the IRQ and CSN labelled ports on the right hand rail are the ones that can receive analog inputs?

Yes.
IRQ = A8
CSN = A1
CE = A0
