INTRODUCTION
A smoke detector or smoke alarm is a device that detects
smoke and issues an alarm to alert nearby people that there is
a potential fire. Smoke detectors can work by optical
detection (photoelectric) or by physical process (ionization),
but some smoke detectors also utilize both types of detector
to increase the sensitivity to smoke [1]-[3]. In this paper,
enhancement done on already available photoelectric smoke
detector circuitry by integrating some distinct features like
wireless technology, sms sending through gsm module and
fire extinguishing vehicle [4]. This features increase the
safety and reliability of the smoke and fire detection
technology
