Read Temperature & Humidity

Call the library to get real climate numbers.

Time to Read

Your sensor is wired and the library is ready. Now you will ask it for real numbers and print them to the Serial Monitor. 🌡️

Call readTemperature() to get the current value in Celsius. Store it in a float because the reading often has decimals.

float t = dht.readTemperature();
