Are there any smoke detector modules available anywhere. In most Indian sites I've seen only gas detectors but not any smoke detectors.
And by the way what is the best way to detect fire. Smoke, temperature or something else?
I wanna use PICAXE the fire alarm project because it is $)cheap $) and it is easier to program than PIC. Which version of PICAXE do you think I should use?
Thanks in advance.
