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

thingiverse

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.)
