🧠 Working Principle

🔐 Gate Control System

RFID cards and keypad passwords authenticate users.
If credentials are valid, the servo motor opens the gate.

🌡 Environmental Monitoring

• DHT11 monitors temperature and humidity.
• MQ-2 sensor detects gas leakage.

💡 Appliance Control

Lights and fans are controlled through relay modules.

Control methods:

• Touch switch
• Bluetooth mobile app
• IoT dashboard

🌙 Garden Light Automation

The LDR sensor detects ambient light and automatically turns on garden lights during night.

🌧 Clothes Protection

When the rain sensor detects rainfall, a servo motor automatically protects clothes from rain.
