What temerpature sensor and how do I use it?

I have a motor with hall effect sensors, but no temp sensor. I was actually thinking of using the temp sensor input from the vesc 6 to monitor my battery temp, since my motor never gets very warm, but my battery is getting very hot.

 

Can anyone recommend a temp sensor that could be used with the vesc for this?

 

I saw someone recommend the Farnell NTCLG100E2103JB in another thread, but I don't see how that is to be wired up.

Any help is much appreciated. Would really like to see what's going on and limit current output when it gets hot before I destroy my $600 headway battery pack.

Thank you in advanced!

You can use any 10k @ 25 degree C NTC you want. You can configure the NTC specific beta value of the NTC in the VESC Tool.

So something like this would work then?

Also, what about about wiring? The way I've seen these used is in-line to turn something off and on based on the temp. The vesc has 1 pin for the temp sensor, so how do I wire this?

A bit big but if it matches your application than you can use it. You should wire it between TEMP and GND. Beta value is 3950
