I use an LM335 to control the temperature of a peltier element. I used thermally conductive paste to pin the LM335 onto the peltier element. I calibrate the sensor with a potentiometer via the adj Pin. So far so good.
I thought I could take quite exact measurements but the sensor seems to deliver quite random values - sometimes ranging from +/- 3 degrees from the actual temperature. (??) How can I get an exact measurement of the temperature? Or should I use another TempSensor?
... the wires to connect the sensor are about 10 cm long.
Thanks for your help!
