Reading lots of thermistors!

Using Arduino LEDs and Multiplexing
#1

Hi,

i would like to build a rig that includes approx. 100 thermistors. I can't think of any solution to read all those efficiently.
Does anybody have any ideas except for 100 analog inputs? :slight_smile:

Are there any cheap digital temperature sensors available that i could read using SPI maybe?

..oh yeah, i would like to measure a temperature range between 100 and 200 degrees C.

Thanks for any help!

Cheers,
ZR

A few 16-port multiplexers?

Exactly…that’s what i was looking for, thank you!

Glad to hear it. The general theory I cover here:
