Hello,
I want to log room and environment temperatures using LM35 and a logomatic V2 SparkFun Electronics - Logomatic v2 Serial SD Datalogger
Sounds easy, but I got say

0 and 0 is input on gound, 360 is a battery and the other two columns are room temperatures. Logged at 1 Hz.
Now the trouble: battery does well, but the temperature readings meant to be around 66 and they would not change by 1°C within one second.
Would I be better off using an amplifier? Or is there some trouble with the ADC inputs, resistance to low? Or pull ups needed? Its reading between 1.7 and 2.8V with open inputs.
Thanks in advance!
