# Indoor Security System

Day 62 of the 100 Days 100 IoT Projects collection. Board: ESP32.

PIR motion plus a 4x4 keypad arm and disarm an ESP32 alarm reporting to Favoriot IoT. A complete DIY security panel.

## How it works

The system sits in armed or disarmed states switched by the keypad code. While armed, PIR motion events trigger the alarm sequence and report up to the Favoriot IoT cloud. Disarm with the right code and it stands down silently. A complete DIY panel: sensor, logic, and cloud reporting.

## What you'll learn

- Security system states
- Arm/disarm logic
- Multi-sensor fusion
- Cloud alarm reporting
