This is simple termometar project with one senzor and lcd. Parts are from Arduino basic kit.

  • Arduino controller × 1
  • USB data cable × 1
  • KY-015 module × 1
  • LCD with I2C interface


I used KY-015 sensor, it litlle bit diferent from DHT 11. Because it espose only 3 legs.

You can find also explanation on shemantic in note.


So if you have KY-015, use like this:

pin 8 --> Pin S module

GND --> Pin - module

+5 --> Pin Middle


Library for LCD is from this link:
