This is a temperature logger to log the temperature over time. I have been wanting to make one of these for a while. It will be used to see how Low and high the temperature during the days away camping. It uses the Plex board from https://tinkersprojects.com/project/plex-controller/ with a DS18B20 temperature sensor. The data from the sensor is logged every second and Additional sensors can be added.
