You can use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out ... if you want to use an LCD. I’ve chosen the DHT22 over DHT11 because it has a ...

In this Arduino Uno based project we are going to measure ambient temperature and humidity and display it on a 16x2 LCD screen. A combined temperature and himidity sensor DHT11 is used with Arduino ...

After downloading the zip file install I2C LCD library in the Arduino IDE by sketch->import library.This library can also be used with Arduino boards for communicating with I2C LCD display modules.

That’s an Arduino wired up to a DHT22 temperature and humidity sensor ($9.95 from The Robot Shop). Using the wiring diagram helpfully provided by Adafruit I connected the DHT22 to the Arduino, with ...
