Final Project Summary:
Here I present a very simple and powerful circuit for a fire alarm security system. In addition, we use NOR and OR gate with three inputs (Heat Sensor, Flammable Gas & Smoke Sensor, Noise sensor). It’ll help us to light up when the danger comes. On the other side, we use an alarm circuit that ensures the incident. Both circuits use only a few passive components and can easily generate a lot of sound from even the most inefficient headphones and there will be no compromise for the quality.

Scope:
This engagement provides security with a standard operational circuit to decrease the rate of death in fire accidents. The engagement also includes low cost than other devices. This device will have limited function. In order to implement this project have a low cost with a few passive components that are easily available and cheap. But the scope of this project is to “SAVE LIFE”.

Schedule:
This engagement began on November 21, 2020 and will continue through December 4, 2020 with the implementation of the system and the first 2 weeks of inventorying the circuit diagram and it’s installation.
Costs:
Hardware costs include the PCB board, RespberryPi 4, with the OP-AMP and other peripheral hardware required at this device hardware. All additional costs have been installation time. It can vary depending on the situation. The overall cost of the project around eight thousand BDT.
Risks:
As outlined in the scope document, the risks are as follows:
Risk | Impact | Probability |
Project components can produce a thread to cybersecurity. | High | High |
The cost can be varied with the situation | Moderate | Low |
Real-life implementation can be tough. | High | Low |
Platform:
Future directions:
Fire detection technologies have been slow to evolve compared to rapidly advancing smart devices. Understandably, global companies focus their efforts on developing high-return products, especially ones that connect consumers with popular trends. While fire alarms aren’t exactly at the forefront of social advancement, innovative companies are developing new methods of approaching fire and gas-related threats.
