Repository Contents: Arduino Code: Contains the source code for the Arduino microcontroller, responsible for smoke detection and control of the DC motor pump and relay. Circuit Image: Provides an ...

Here we have used Buzzer as a Smoke alarm, which is driven by BC547 NPN transistor. We have previously built Smoke Detector Arduino Shield using MQ2 Gas Sensor, which not only sense the smoke in the ...

Flame Detection: The flame sensor continuously monitors the environment. When it detects a flame (or significant heat source), it sends a low value to the analog pin on the Arduino. The system reacts ...

I will attach all the schematics and the PCBs design for the project. I will start by doing the PCB design for the smoke sensor detector. Components: Arduino UNO; Power Supply; Smoke Sensor (MQ2) ...
