The Complete Beginners Guide to Arduino - 2021 - Temperature and Humidity Sensors - DHT11

This video tutorial explains how to use the DHT 11 temperature and humidity sensor with an Arduino. It covers the differences between DHT 11 and DHT 22 sensors, setup instructions, and how to use the Adafruit library to read data. The tutorial also addresses handling invalid readings and calculating the heat index. Finally, it demonstrates how to format and print sensor data to the serial monitor.
