Resistance Temp Sensor

Other Hardware Sensors
1

Sorry newbie here, just brought my first arduino and have a PTC temperature resistance sensor i would like to serialprint.

Just after any ideas on how to get this going.

Thanks in advance.

You should tell what you really want to do, and what you tried already.

(and look up some NTC/PTC tutorials - NTC is probably more common, the principle is very similar).

Thanks, the plan is to log the data from a farm milk vat at 1 minute intervals. This sensor DANFOSS EKS 111 is the certified temperature probe we can use with these sealed stainless steel vats.

I have yet to purchase any resistors yet and am not sure if these are required.

This is the reading I have done so far

You should also read the sensor's data sheet. Usually has lots of useful information on how to hook it up, what resistance values relate to which temperature, technical limits (temperature, voltages), etc. As it's a certified sensor there must be a lot of information from the manufacturer in it.

Yes it has all these, I am ok with the code side of things, just unsure on the physical setup, ie will it require a resistor

Most likely yes - and the data sheet should tell you exactly what value and how to wire it.

A "waterproof DS18B20" looks almost the same.
Easier to use than a thermistor, factory calibrated digital output, and probably cheaper.

Did you read the company's instruction that the sensor is NOT to be used to measure temperatures for food safety purposes?

Thanks guys, in retrospect best to just get an DS18B20.

Looks a lot easier
