To run:

1. Follow steps at https://randomnerdtutorials.com/guide-for-ds18b20-temperature-sensor-with-arduino/ to install OneWire and Dallas Temperature libraries in the Arduino IDE
2. Compile and upload code to the arduino. Set the correct port if not connected at '/dev/ttyUSB0'. The default wait time between measurements is 10 seconds - adjust this as needed
3. Install needed python libraries:

pip install pyserial

4. Run the python code to log data. It will be saved as a .csv in the folder 'data':

python read_and_save_serial_temperaturedata.py

The python code starts a new csv file each day, and appends to current files so they can be viewed as the code is running.
