Description

Fire Alarm System with Arduino Nano

Hello!

This is a simple project made with Arduino Nano and some common modules. I used an infrared flame sensor, an MQ-2 smoke / gas sensor, an audible warning buzzer, a relay that could control a sprinkler, a digital display and an On / Off button. As many modules are used for this project, I did not pay too much attention to the positioning of the parts, jump wires are needed.

Note: Pay attention to the polarities, and to the positioning of the flame sensor, normally short leg is connected to a power supply and the long one to ground through a resistor. This is a prototype so changes may occur.
