：Description
for this project i used:
Arduino UNO
Smoke Detector
Power Supply.
In this Smoke Detector Circuit with Arduino, I used a MQ2 Gas Sensor to detect preset smoke in the air. A 16x2 LCD is used for displaying the PPM value of Smoke. And an LM358 IC for converting smoke sensor output into digital form (this function is optional). A buzzer is placed as an alarm which gets triggered when smoke level goes beyond 1000 PPM.
Attached below is the program for the circuit and the gerber file
