hi everyone, i wanted make an circuit with an pic 18f2550 for read of temperature and drive some loads. until today i used for this purpose always the temperature sensor lm35dz, but now i need of to use an ntc sensor .
comparated to lm35dz , the ntc is not have linear values .
haven't the data sheet of the ntc, but i can do some test and take some values at determinated temperatures , help me with an termometer .
for now i kwon that at 18 ˚c it have an value of 6,5 kohm .
on the component there are some values written that i report:
S+M 1
K276/4,8k/A6
5500 001 148
somebody can give me a formula for calculate this value in way that i can use it.
thank you so much
