Thanks for the info on the LM35, I had been using thermistors but the LM35 might be better. Which package do you prefer to use? The TO-92s or the TO-220s?
I have a kit to put together a shield for a datalogger system, I have not yet put it together or even unpacked it. I need to log gps data and NMEA depth sounder data for a work project. I may also try to put together a pothole detector to rate city streets as to bumpiness as the driver experiences it.
It is an inexpensive kit:
