High temperature sensor (Arduino)

[Joseph993]

Hi is there any recommendation for a high temperature sensor that can be connected via arduino? For measuring of Nickel Cadmium battery.

Thanks in advance!

NTC thermistors are cheap and generally go to 125° C or 257°F

it depends on a single term "high tempreature"
there are many out there, as coca cola said thermistors are good. I have also seen non-touch infared laser do the same. and yes there are kits already for them. I personally like jaycar in australia, as they have the kits, but typing in arduino temperature sensor into any search engine will get you tonnes of replies.
just try to figure out what range you need it for then you can narrow down your search alot

If you want dirt cheap and want it to have some 'wow 'factor, use a diode

Just Google 'diode temperature sensor'

By "High temperature", Joseph993 possibly means "Over temperature" or similar. I don't imagine he wants to detect when they hit 600C (which really is "High temperature").

The most common solution is to place a thermistor in contact with the batteries.

Back in my RC car days before it became cool and trendy and before Lipo, when you had limited choices with a lot of them being hobbiest brewed hardware, my charger had a thermistor attached to a copper plate that you rubber band to the battery pack when charging to detect full charge, I remember having to toss the batteries in the freezer if I wanted fast rotation from high use to charge or else it would trip the sensor prematurely and not charge...
