About this project

Intro

I built an Arduino Weather Station. It uses a DHT 11 (it will also work with DHT21 DHT22).

Build a Reliable Arduino Weather Station with DHT Sensors

Video

I explain everything in this video. So it might be easier for you if you watch it!

First Sketch

Build a Reliable Arduino Weather Station with DHT Sensors

The first sketch displays the sensor values to the Serial Monitor.

Sensor:

  • pin 1 - 5
  • pin 2 - 5v
  • pin 3 - GND

Second Sketch

Build a Reliable Arduino Weather Station with DHT Sensors

In this sketch we are going to display the values onto an LCD. I used an I²C LCD for this project.

Sensor:

  • pin 1 - 5
  • pin 2 - 5v
  • pin 3 - GND

LCD:

  • SDA - A4
  • SCL - A5
  • GND - GND
  • VCC - 5V

Third Sketch

Build a Reliable Arduino Weather Station with DHT Sensors

The final sketch also displays a realtime clock to the LCD. It uses a DS1302 module. For more information about this clock you can check out the Arduino clock I made in a previous project.

Sensor:

  • pin 1 - 5
  • pin 2 - 5v
  • pin 3 - GND

DS1302:

  • RST - 2
  • DATA - 3
  • CLK - 4

LCD:

  • SDA - A4
  • SCL - A5
  • GND - GND
  • VCC - 5V

Code

The code can be found by the CODE part of this project. Libraries are in a map. You have to first unzip the map. Then install them.
