Скачать или смотреть Arduino DHT11 Sensor with LED Temperature and Humidity Based LED Control

🚀 Welcome to another exciting Arduino project! In this video, I demonstrate how to use the DHT11 Temperature & Humidity Sensor with an Arduino to control an LED. This project is perfect for beginners who want to learn how to automate electronic devices based on environmental conditions.

🔎 What Happens in This Project?

The DHT11 sensor reads the current temperature 🌡️ and humidity 💧.
If the temperature exceeds a set limit (e.g., 30°C), the LED automatically turns ON 🔥💡.
If the temperature drops below the threshold, the LED turns OFF ❄️✅.
This technique can be used for temperature-based automation in homes, industries, and smart systems.
🔧 Components Used in This Project:
✅ Arduino Board 🎛️ (Uno, Mega, or Nano)
✅ DHT11 Temperature & Humidity Sensor 🌡️💧
✅ LED 💡 (to indicate temperature status)
✅ 220Ω Resistor 🔩 (for LED protection)
✅ Jumper Wires 🔌 (to make connections)

📜 Step-by-Step Explanation:
1️⃣ Wiring the DHT11 Sensor 🛠️

Connect VCC of DHT11 to 5V on Arduino
Connect GND to GND
Connect Data Pin to Pin 13
2️⃣ Connecting the LED 💡

Connect the positive leg (anode) of the LED to Pin 2
Connect the negative leg (cathode) to GND through a 220Ω resistor
3️⃣ Writing & Uploading the Code 💻

Use the DHT library to read temperature values
Compare the temperature with a threshold
Turn ON/OFF the LED based on the reading
Upload the code and test it in real-time 🚀
