This project is a Smoke detector mini project using 8051 microcontroller. In this mini project, we have used MQ series Smoke sensor to detect the Smoke caused due to fire. Output of smoke sensor is in analog format so it is given to the comparator IC.
Buzzer is turned on when smoke is detected. LCD display shows the respective message in case of smoke detection. This low cost smoke detector can be used in our Home, schools, colleges and companies.
