Hello world! Today i made a simple Temperature & Humidity Meter with the TM1637 7 Segment Display & DHT11 temp sensor. Follow the next step for the Schematic, Code & Parts list.

This is very easy to build, I made it because i have no temperature meter at the attic. SO a simple cheap option is to build this simple device with arduino.

Thank you!!!
Been looking such a long time for a simple humidity meter with LED segment display for a project. Simple and great instructions. Wish I found this instruction much earlier :-)
