🛠️ How It Works

1️⃣ Reads temperature via digital thermistor
2️⃣ Measures humidity using capacitive sensing
3️⃣ Sends digital data through a single data pin for real-time monitoring

📲 Display data on an LCD, upload to cloud, or trigger fans/pumps based on readings!

🧠 Pro Tip: Prefer DHT22 over DHT11 when you need better accuracy and wider measurement range!
