Data logger with the Arduino Uno

• Collects data with a sensor
• Stores data in an array
• Communicates with PC over serial port
• Saves data to a file

I used:

• Python for UI
• DHT22 sensor to read temperature and humidity data.

Data is saved with a timestamp to:

• root/data_temperature.csv
• root/data_humidity.csv

Example of a single data reading: 2020-06-03 23:58:51.973248,23.10,23.20,

Getting started:

1. Install Pandas:

   • https://pandas.pydata.org/pandas-docs/stable/getting_started/install.html

2. Upload sensor/sensor.ino to Arduino connected to DHT22

3. Download the DHT sensor library to Arduino libraries

   • https://github.com/adafruit/DHT-sensor-library

4. Run the program in the root directory:

   • python sensor.py
