Temperature and Humidity Monitor w/ Graphing - 5110 Display - DHT22

thingiverse

This little project showcases the current humidity and temperature on a 5110-Nokia LCD display. It also logs the temperature for the past 60 seconds, minutes, and hours. Based on this data, a graph is drawn on the lower half of the screen. The user can select from three different backlight modes. To measure relative ambient light, a photoresistor is used. There's enough space inside the case to accommodate an 18650 cell and charging circuitry. This device is extremely comfortable to hold and quite portable. I used a 5110 display with a blue PCB that is slightly larger than the red versions. This doesn't cause any issues, but the screen will not be held in place as securely. Code for this project can be found on GitHub at https://github.com/wilhelmzeuschner/arduino_temp_graph. If you build this project and want to show your appreciation, I'd love to see a post under "Makes"!
