I'm thinking about a project for a set of remote temp sensors for where my dog sleeps in the garrage under my workbench.

The outside temps here can range from near -10 to +115 give or take.

My electronic project skills are kind of limited but would like to see how I may do this.

It could also serve as a early warning for when the Heat lamp and heated bed give out.

I have found a few projects on line but no super detailed instructions.

(I wasn't sure what tag to use on this so I put

Any Ideas ?

Thanks for your time.

If you're still interested, National Semiconductor used to make a broad line of analog ICs at a reasonable price, including a cheap, 4-pin temperature sensor called a LM20. Since Texas Instruments bought out (and destroyed) this excellent company, you have to deal with them now. Try this link:

Temperature Sensor Eval Board[^]

It contains three sensors, and connections to the outputs of each. There are also links to application notes, which usually offer complete reference designs free for your use.
