This project is to develop a wireless security control system for smoke and fire detection. The purpose of this project is to detect the fire and transmit information by using wireless network. The requirement for the project is to design and to create a functional smoke detector. After detecting smoke or a high temperature (potential fire), the detector sets off the appropriate alarm sound. The detector also transmits an RF signal to the other smoke detectors in the network so that those detectors, in turn, sound their alarm. Each detector is capable of sounding four different alarms. There is a smoke, temperature, low battery, and received alarm.

Fire Detector Wireless Security Control SystemThe smoke detector is one of three items of fire safety apparatus that are recommended for homes and that can be installed by the consumer. The second is a fire extinguisher and the third is a fire blanket, a section of fire retardant cloth, normally 1 meter (3.3 ft) on each side that can be applied to a small fire to smother it. The motivation behind the project came from brainstorming and thoughts regarding bolstering home safety. The importance of smoke detection is one of the chief safety concerns for residential (single-family) housing. Most smoke detectors on the current market are individual units sans communication or connections to the other smoke detectors. Thus, only the smoke detector that sounds an alarm is the one which senses the smoke. The solution is a wireless implementation of smoke detectors increasing safety in terms of saving lives and property. In the incident of a fire, residents are alerted more rapidly as response time is decreased, thereby increasing the chance for survival.

Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), but some of them use both detection methods to increase sensitivity to smoke. These smoke detectors are both used to detect fire, but not the same type of fire. Photoelectric Smoke Detectors are faster in detecting smoldering fires, while Ionization Smoke Detectors are better at detecting flaming fires due to their ability to detect smaller particles.
