Mission Briefing
By the end of this mission, you will be able to:
Explain what a DHT sensor measures and how it communicates with the ESP32
Describe the difference between DHT11 and DHT22 sensors
Wire a DHT sensor to the ESP32 correctly
Use a library to read and display temperature and humidity
Weather apps, thermostats, and smart home hubs all rely on one thing: a sensor that can measure temperature and humidity. In this lesson, you'll meet the DHT sensor and use it to bring real-world weather data straight into your code.
Robo says: “Up until now, your circuits have reacted to light, distance, and buttons. Today, your circuit learns to feel the temperature and humidity around it.”
