How to make a Fire Alarm with Arduino
In this tutorial we will learn how to make a Fire Alarm Using Arduino and Flame Sensor.
For this tutorial we will use Flame Sensor, Led, Buzzer and Arduino UNO.
Hardware Required :
- Flame Sensor
- Jumper Wires
Project circuit :
Project circuit diagram is shown below.
How Flame Sensor Works
These sorts of sensors are used for brief range fire detection and may be wont to monitor projects or as a security precaution to chop devices off / on.
The flame sensor is extremely sensitive to IR wavelength at 760 nm ~ 1100 nm light.
Analog output (A0) : Real-time output voltage signal on the thermal resistance.
Digital output (D0) : When the temperature reaches a particular threshold, the output high and low signal threshold adjustable via potentiometer.
- VCC — Positive voltage input: 5v for analog 3.3v for Digital.
- A0 — Analog output
- D0 — Digital output
- GND — Ground
