Serial USB Temperature Data Collector

Icon

This is a repository that collects files related to my tutorial on how to use Python to collect and save data from a microcontroller to your PC. This program is available for macOS High Sierra or Windows 10 (see the releases page to download) and can be used to collect temperature data from the Teensy-based temperature collector I outline in my tutorial. It looks like this:

Wiring diagram

Dependencies

You will need to install PySerial (I recommend using pip) and Python 3 to run this code. PyInstaller was used to create the binaries on the releases page. The Arduino IDE and the Teensy packages are needed to flash the Teensy with the serial_temperature_sensor.ino sketch, which collects temperature information from the sensor and then prints it to serial in Celsius or Fahrenheit.
