how to use temperature and humidity sensor with arduino

Arduino - Humidity Sensor - Arduino Project Hub

May 28, 2019· Humidity Sensor (DHT22) The DHT-22 (also named as AM2302) is a digital-output, relative humidity, and temperature sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and sends a digital signal on the data pin. In this example, you will learn how to use this sensor with Arduino UNO.

Displaying Temperature and Humidity on an LCD - Arduino ...

Introduction. In this project, we are going to interface a DHT11 temperature and humidity sensor, and display the data on a 16x2 LCD. If you haven't read Project 9 for the Arduino Uno Rev3, please read that first because this covers how to interface a 16x2 character LCD in 4-bit mode. We will then swap out the 16x2 LCD for a 20x4 LCD to display ...
