Automatic Smoke Detector Alarm

Automatic Smoke Detector Alarm

The Automatic Smoke Detector Alarm is a compact and cost-effective fire detection system designed to alert occupants in the event of a fire. Instead of using expensive commercial smoke sensors, this system utilizes a pair of Infrared (IR) transmitter and receiver sensors. These IR sensors continuously monitor visibility in the surroundings. When smoke obstructs the path between the IR pair, it triggers a buzzer alarm through a 555 Timer IC, alerting individuals nearby.

This system is especially useful in homes, offices, shops, or storage areas where early detection of fire-related smoke can prevent major accidents and save lives.
