# 🧠 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

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

### Telemetry (15 Seconds)

```json
{
  "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

* **AP Name**: MR60FDA2-SUITE5
* **Password**: 12345678

### MQTT Commands

* `relay_on` → Turn lamp ON
* `relay_off` → Turn lamp OFF
