i am using the infrared as the smoke detector,but the problem is i dunno how to reduce the voltage so that whenever it detect certain type of smoke(cigarette smoke),it will become "4.5V" and send the signal to the PIC,then only the PIC will started to record down the total amount of cigarette that being detected.
and everytime the smoke is detected,the LCD will display somekind of message like "dun smoke,its bad for u" ,and at the same time the buzzle will sound.
and another subsystem of my project is the user can use a push button to display the statistic that showing the amount of number that the cigarette is being detected.
all my project is just a prototype project,once if all this problem is settle,then my problem can consider solved.
i need an urgent help now,if anyone of u is able to help me out by teaching me how to write the source code for my system or able to write it for me,please let me know as soon as possible,because i am in a very critical condition now,thanks....
