Flame Alert Servo
Motors · Board: ESP32 · Day 82 of 100
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
