⚙️ Features

🚗 1. Automatic Door System

• Uses Ultrasonic Sensor to detect object/person
• If distance ≤ 10cm → Door opens
• If distance > 15cm → Door closes
• Controlled using Servo Motor

🔥 2. Gas Leakage Detection

• Uses MQ-2 Gas Sensor
• If gas level exceeds threshold (800):
  • Buzzer turns ON
• If safe:
  • Buzzer turns OFF

💧 3. Automatic Water Tank Control

• Uses Water Level Sensor
• If tank FULL:
  • Pump turns OFF
• If tank NOT full:
  • Pump turns ON
• Controlled using Relay Module

🧠 Working Logic

The ESP32 continuously monitors:

• Distance from Ultrasonic sensor
• Gas levels from MQ-2 sensor
• Water level status

Based on sensor readings, it automatically controls:

• Servo Motor (Door)
• Buzzer (Gas Alert)
• Water Pump (Relay)
