The article provides a guide on how to use a DHT11 temperature and humidity sensor with an Arduino. It details the necessary components, wiring, and code required to read and display data from the DHT11 sensor on the Arduino's Serial Monitor.

Key Points:

1. Components Needed: Arduino (e.g., Uno), DHT11 sensor, jumper wires, breadboard (optional), and a resistor (optional).
2. Wiring: Connect the DHT11's data pin to Arduino's digital pin 2, VCC to 5V, and GND to ground.
3. Code: The article provides an Arduino sketch that reads temperature and humidity values from the DHT11 sensor using the DHT library. The data is displayed on the Serial Monitor every 2 seconds.
4. Error Handling: The code includes a check to ensure valid readings, printing an error message if the sensor fails.
5. DHT11 Specs: The sensor measures humidity (20%-80% with ±5% accuracy) and temperature (0°C-50°C with ±2°C accuracy) with a resolution of 1°C and 1% RH.

To use the setup, upload the sketch to the Arduino, open the Serial Monitor, and observe the readings.
