Note that the ultrasonic sensor will pause the program when it is working, which may cause some lagging when writing
complex projects.
1.29 5.13 Temperature - Humidity
The DHT11 is a temperature and humidity sensor commonly used for environmental measurements. It is a digital
sensor that communicates with a microcontroller to provide temperature and humidity readings.
In this project, we will be reading the DHT11 sensor and printing out the temperature and humidity values it detects.
By reading the data provided by the sensor, we can obtain the current temperature and humidity values in the environ-
ment. These values can be used for real-time monitoring of environmental conditions, weather observations, indoor
climate control, humidity reports, and more.
