Overview:

The IoT Smart Elevator System is a modern elevator solution that enhances safety, automation, predictive maintenance, and remote monitoring. It uses sensors, microcontrollers, and cloud connectivity to monitor elevator usage, detect faults, optimize floor stops, and allow remote diagnostics. This system is particularly useful in commercial buildings, smart homes, and high-rise apartments to ensure smooth and efficient elevator operation.

Key Features:

• Real-Time Monitoring:
  Monitors elevator position, status (idle, moving, fault), and direction in real-time.

• Fault Detection & Alerts:
  Detects abnormal vibrations, overloads, or door jams and sends alerts immediately.

• Remote Access Dashboard:
  Admin or maintenance team can monitor elevator status via web or mobile interface.

• AI-Based Predictive Maintenance (Optional):
  Uses ML to analyze sensor data and predict component failure before it happens.

• Smart Access Control (Optional):
  Users can request the elevator using a mobile app or RFID card, reducing touch interactions.

• Usage Analytics:
  Shows data like peak usage hours, total trips per day, or floors most accessed.

Technology Stack:

• IoT Hardware:

  • Microcontroller: ESP32 / Arduino + Wi-Fi module

  • Sensors: Accelerometer (for vibration), Load cell (weight), IR sensors (door open/close), Ultrasonic (position detection)

  • Actuators: Motors for lift movement, relay for control

  • Display: OLED/LCD showing current floor

• Backend:

  • PHP / Node.js / Java with REST API

  • Data collected from elevator is pushed to cloud/server at regular intervals

• Frontend:

  • HTML, CSS, Bootstrap, JavaScript for a real-time dashboard

  • Optional mobile app using JavaScript (PWA) or Android (Java/Kotlin)

• Database:

  • MySQL / MongoDB for storing elevator status logs, maintenance alerts, user logs

Modules:

1. Elevator Control Module:
   Handles commands like move up/down, stop at floor X, open/close door.

2. Sensor Feedback Module:
   Collects data on current position, load, door status, vibration, etc.

3. Fault Detection Module:
   Analyzes sensor data to detect issues like overloading, sudden stops, or mechanical failure.

4. Alerting System:
   Sends alerts (SMS, email, app) to maintenance staff on faults or emergency stops.

5. Admin Dashboard:
   Shows real-time elevator movement, health status, usage reports, and fault history.

6. User Interface (Optional):
   Allows building residents to call the elevator via phone app, view ETA, or reserve a floor.
