Getting started with the DHT22/AM2302 Digital Temperature And Humidity Sensor Module

In this tutorial you will learn how to use this sensor with Arduino uno. The room temperature & humidity will be printed to serial monitor

Step1: Hardware required

Step2: Connecting the Hardware

Follow the next schematic diagram to wire the  DHT22 temperature and humidity sensor to the Arduino.

Step3: Setting up the library

we’ll use the DHT library from Adafruit. To use this library you also need to install the Adafruit Unified Sensor library.

Step4: Upload the sample sketch

open the sample sketch that is located in file>examples>DHT sensor library>DHTtester. and upload it. as shown below

Step5: Testing the circuit

open your serial monitor by clicking on the icon in the right top corner(like search icon)
