    Hi,

     

    Well this one is very easy. We recommand to start on your own instead of ready code. For this application you need following hardware and software.

     

    1. 8051 developemnt board (you can design your own also)

    2. Smoke detector (easily available in market)

    3. Buzzer

     

    Keil & Flashmagic Software

     

    Algorithm for this application is mentioned here

     

    Connect Smoke detector output on any controller pin and buzzer on another pin

    Monitor that pin continuosly untill you receive signal on that.

    Give signal on buzzer

     

    That’s it…

     

    Start it and if you have any queries, write me back….

    u can use LDR for this purpose. because as smoke increases the light falling on LDR decreases and its resistance increases. so you bias LDR with fixed value resistor and take output across LDR. the output voltage across LDR changes. that can be interpreted as smoke level
