Temperature and Humidity Logger

🚀 Overview

To read temperature and humidity data using DHT22 sensor and Arduino UNO and logs it to the serial monitor.

🛠️ Components

• Arduino UNO
• DHT22 sensor
• 10kΩ Pull-up Resistor
• Jumper wires

💾 Installations

1. Install the 'DHT' and 'Adafruit Unified Sensor' libraries.
2. Upload the code to the Arduino using Arduino IDE.
3. Open the Serial Monitor to view the data.
