Description
Yet another thermometer with humidity sensor.
Sensor:
HTU21D
Display:
TM1637
Arduino Nano
Fusion360 file and Arduino code included.
Just rename it from nano_TM1637_HTU21D.txt to nano_TM1637_HTU21D.ino
There is some wall mount optional holders as well, you do not have to print them if
you will not use them.
Display will cycle Temperature and Humidity values in cca 3 seconds interval(you can change it in code if you want).
There is no need to include schematics as it is very simple and you can find wiring of sensor and display in Arduinos code:
Display:
define CLK 6 // Display CLK
define DIO 5 // Display DIO
