# Flame Alert Servo

Day 82 of the 100 Days 100 IoT Projects collection. Board: ESP32.

A flame sensor triggers an SG90 servo alarm on the ESP32. Fire detection with a physical response.

## How it works

The flame sensor watches for the infrared signature of fire; on detection the ESP32 drives an SG90 servo as a physical alarm — waving a flag or striking a bell. Light sensed, motion answered: a safety system with a moving part instead of just a beep.

## What you'll learn

- Flame IR detection
- Alarm actuation
- Sensor-to-servo response
- Physical alarm design
