Hi Guys,
I have hooked up my LM335 temperature sensor to my system and I am getting some funky readings. Basically if I heat up the sensor the temperature reading I am getting in my serial port is going down.. i.e. the wrong way.. Has anyone run into this problem before?
I am certain that the code is fine because it has indeed worked in the past.. For your reference here is how I am calculating the temperature:
tempC = (((500*analogRead(tempPin))/1024)); //convert the analog input to a temperature in Celsius
Anyhelp MUCH appreciated!
Thanks!
Clarke
