Hello Everyone
Does anybody have any experience with Thermistors?… I am planning to develop a circuit to regulate the temperature of a soldering iron and would like to use a Thermistor and a PIC to test what range the temperature is in:
<50 C
50 - 225
225 - 260
260 - 290
290 - 325
(resolution is not a major issue – precision could be as loose as plus or minus 10 degrees C).
Obviously I need a Thermistor with a temp range of at least 0 to +325 degrees C. and was recommended that to use with a PIC with no additional signal amp it should be around 1k at room temperature.
Does anybody know where I would find a Thermistor that can deal with these ranges? The most I can find only go up to 125 degrees C.
Also has anybody ever designed a temp testing circuit using Thermistors that could give me any pointers (this will be the first circuit I’ve designed as I have very little electronics experience).
Thanks everyone.
Adam.
