In this section, we'll build a simple program to read temperature and humidity from sensor devices. We'll use the DHT22 sensor module for this. This sensor device is easy to find on online stores such as Adafruit, SparkFun, and AliExpress.

Our project scenario is to read temperature and humidity values from a sensor device. Then, we will print sensor values on a serial Terminal. After doing this, we will implement our hardware wiring and develop a program.
