Guitar Case Humidity Alerts

Final Project - Guitar Case Humidity Alerts

For this project, I decided to make something that I can use in everyday life. I took my Raspberry Pi 3 B+ and my Arduino Nano with a Humidity sensor to create a system that sends me a text message when my guitar case has an unsafe humidity. This is when it's outside the range of 40-50 percent humidity.
All code for this project can be found at this GitHub repository.

How to Play

• The program is started by turning on the Raspberry Pi which is connected to the Arduino via a USB Serial cable. Then running the "Raspberry.py" python file (with sudo) on the Pi.
• The program polls the Arduino every few seconds, and when the humidity goes out of safe ranges, it sends an email to AT&T's Email-to-Text service which sends my phone a text message.
• It only sends a text once while outside of the range to avoid spamming texts.
• Once Humidity returns to safe levels it then sends another text alerting the user.
