This little project displays the current humidity and temperature on a 5110-"Nokia" LCD.

Additionally it records the temperature of the last 60 seconds, minutes and hours.

Based on this data, a graph is drawn onto the lower half of the screen.

The user is free to choose between three different backlight-modes.

In order to measure relative ambient light, a photoresistor is used.

There is enough room for an 18650 cell and charging circuitry inside the case.

This device is very comfortable to hold and quite portable.

(I used a 5110 Display with blue PCB which is slightly larger than the red versions. This is not a problem but the screen will not be held in place so nicely.)

If you build this project and want to give me something back in return, I'd be extremely happy to see a post under "Makes"! :)
