This is very similar to Lesson 17 – Thermometer.
A temperature humidity sensor is commonly used in environmental monitoring
The Circuit
Program Description
This Arduino program reads temperature and humidity data from a DHT11 sensor and displays it on an LCD screen.
The program begins by initializing the LCD and clearing its content.
In the main loop, it continuously reads sensor data every second, displays the humidity on the first line of the LCD and the temperature on the second line.
The cycle repeats, allowing for real-time updates on the LCD.
See the flowchart below for more information.
