🧠 Smart Room IoT Monitoring – MR60FDA2

📡 Sistem IoT untuk deteksi keberadaan manusia, fall detection, dan otomatisasi lampu menggunakan mmWave Radar, sensor cahaya, dan MQTT.

📌 Overview

Project ini merupakan sistem IoT Smart Room berbasis ESP32/ESP8266 yang menggunakan Seeed MR60FDA2 mmWave Radar dan BH1750 Light Sensor. Sistem mampu mendeteksi keberadaan manusia, kondisi jatuh (fall detection), serta mengontrol lampu ruangan secara otomatis berdasarkan intensitas cahaya. Data dikirim dan dimonitor melalui MQTT.

Project ini terinspirasi dan disusun dengan gaya dokumentasi seperti repository IoT pada umumnya dan cocok untuk Smart Building, Smart Hotel, maupun Capstone Project.

📡 MQTT Payload Format

Status Change

{
  "event": "status_change",
  "room_id": "SUITE-5",
  "nilai_sensor": 0,
  "status": "PEOPLE"
}

Telemetry (15 Seconds)

{
  "telemetry": true,
  "room_id": "SUITE-5",
  "nilai_sensor": 0,
  "status": "NO_PEOPLE",
  "lux": 8.7,
  "rssi": -67
}

🧠 System Logic

Lamp ON if:
- Human detected or fall detected
- Light intensity < 10 lux
Lamp OFF if:
- No human detected
- Light intensity ≥ 10 lux

🎨 LED Indicator

Status	Color
PEOPLE	🟢 Green
PEOPLE_FALL	🔴 Red
NO_PEOPLE	🔵 Blue

🌐 WiFiManager
