  basically, u'll need a smoke/fire detector(sensor), a comparator(example- an opamp) and a output load(to notify the smoke alarm- perhaps an LED or a buzzer)
  
  measure the voltage accross the sensor initially when there's no smoke(V1 volts),
  now measure the voltage accross the sensor when there's smoke around it(V2 volts).
  Give V2 volts as reference voltage to an inverting input of the op-amp,
  and give the sensor output, as a input to the non-inverting input of the op-amp,
  
  Now, as the sensor senses the smoke, the buzzer will sound or the LED will glow

  Hello CEan,
  Actually if you are very keenly interested in building one,just try visiting any manufacturers because you will definitely get more of intense knowledge but i understand that you will not have an easy chance to visit one but just try out if you can!
