Design Analysis and Implementation of Automatic Fire Extinguishing System Using ATmega16 Microcontroller as Control

Aim: The aim of this research is to design an automatic fire detection and control.

Methodology: The system consists of two sensors, microcontroller, buzzer and a pump/sprinkler. An LM35 integrated chip has been used as temperature sensor while MQ-2 gas sensor has been used as smoke sensor. All sensors are connected to the microcontroller through an input/output port. The controlling software for the whole system was designed in C programming language. The popular high performance, low power 8-bit microcontroller from the AVR family microcontrollers has been used. The system was finally tested by introducing fire parameters (smoke and temperature) close to the smoke and temperature detectors respectively. When the parameters go above the set level in the detectors, audio alarm, light indicator and pump/sprinkler were activated. The measured temperature of the system was compared with the reference temperature.

Results: The result showed that there was a mean deviation of 1.550C between the measured values and reference values which served as the control.

Conclusion: The constructed system is compact and easy to install. The constructed fire control device is quite cheap and affordable to every category of person.
