Hardware components

Arduino UNO

USB-A to B Cable

Adafruit Waterproof DS18B20 Digital temperature sensor

or other sensor (optional)

Software apps and online services

Arduino IDE

Story

Unodatalogger is software for arduino to acquire data over time. You can acquire the voltage or the value of a sensor. (temperature, humidity, light….)

Work under windows or linux ( tested on linux mint 19)

Setup the Arduino

Connect arduino uno to pc with usb cable

Upload example ino or modify sketch

Run software on PC.

Choose serial port.

Connect arduino

Choose sampling time and numbers of points. Run You can save data to text file or chart image
