Hello,
I have make a digital termostat with a LM35dz. So all work well untile the
temperature around the probe stay above 7 degree, but when the temperature falling down under the 7 degree i will get a very instable measurement. I have tried to change the pics(16f676) the lm35 the cable the tension(5v) but i get alway the same instability below 6/7 degree.
Have you any idea where is the problem ? Maybe i need to put some condenser o resistance on lm35 pins ?
Thanks for read.
