In this Instructable I'm going to teach you how to make a small station to measure the local tmperature and humidity and displaying it on the display.
So why did I do this?
My dad asked me if I could do some kinda sensor that measures the temperature and humidity in his office, but as it won't be able to use the wifi there it should only display the measurements directly..
Teachers! Did you use this instructable in your classroom?

Step 1: Stuff You'll Need
Step 2: Preparation
Make the wiring as show in the picture and check with the sketch from the next step that it works.
Also you might print the two parts for the casing(the two .stl files)
Step 3: Arduino Sketch
Here is the sketch for the arduino nano which you need to flash on the mcu.
The GitHub version can be pulled here or just downloaded from this instructables.
For how it works check out the commends even though they are german, the translator can help you.
Step 4: Putting It Together
- Hotglue the Arduino Nano into the case, so that you can still plug it in from the outside through the small whole.
- Glue the DHT11 Sensor into the small front whole with some hotglue
- Hotglue the TFT display onto the front cover so that it fits with the black bessels (turn it on to see them better)
- Use the superglue and glue the front cover onto the case.
