There are various reports of LPG related fires, and accidents during a gas leak event. Most countries have paid great attention to LPG gas monitoring, because gas leak may cause serious accidents and casualties to people’s lives and properties. Due to the increasing reports, concern in proper monitoring is seen as one of the viable solutions.
The main objective of the study was to design and develop a LCD gas leakage monitoring system that automatically monitors and display warning when a certain amount of gas is monitored in a storage room. The system uses sensors called MQ-5 and MQ-6 which will be the main part of the system. In addition, we include a buzzer which will be placed outside the room. The result will be displayed in a LCD display.
The LPG gas monitoring system is consist of a hardware and a software. The hardware involves the MQ-5 and MQ-6 sensors, the buzzer, the LCD, and the Arduino Uno as our microcontroller. Software was developed in order to program and display the data gathered by the sensors that will be displayed in the LCD.

This research paper contains the computation and design of an Inverting Operational Amplifier with the given specifications. In Inverting Operational Amplifier circuit, the operational amplifier is connected with feedback to produce a closed loop operation. The document shows the simulation and computation of the parameters needed for the Inverting Op Amp. It also presents the actual design of the amplifier which is prototype in the breadboard. The group also use the NI Multisim 14.0 for the simulation and design of the designed Op Amp. The study also shows the discrepancy between the simulation data and the computation data by calculating the percent difference of the two data.

This project is focusing on the design, fabrication and testing of an rectangular micro-strip antenna. This involves choosing a suitable microwave substrate available in the market readily for fabrication and further development. The design involves finding the width and length for a wide micro-strip rectangular type and suitable thickness. We found that PCB material with both sides copper clad is available with a dielectric constant and thickness. This will be fabricated by using printed circuit board technology. Then the electrical measurements like antenna input impedance, VSWR, Return Loss, Reflection Measurements will be carried out by using a vector network analyzer and also this measurement will give the antenna parameters of bandwidth. Finally the theoretically calculated values are compared with the measured performance parameters of the antenna and the difference is analyzed.

The Anti Vehicle Theft Detection is a system or device made by the group, the A-Team that can help people for tracking and securing their vehicle to avoid vehicle theft. For this system, it would not only help the people living in this time, but also the future generation and the future researchers that will be studying on how to improve the quality of safety for vehicle owners.
In this project, the group developed a system wherein vehicle tracking system and vehicle theft detection is possible. The group used different kind of components for the building of the device. The main component for the device is the NodeMCUas the microcontroller of the system. It commands the other components connected to do its function to track the vehicle and sends the tracking data over through an application called Blynk. The main purpose of this project is to prevent vehicle theft.

The field of firefighting has long been a dangerous one, and there have been numerous and devastating losses because of a lack in technological advancement. Even though fire fighters are trained extensively in this line, there still an undeniable danger to their lives. With the advancement of technology, this paper presents a possible solution through designing a fire firefighting robot which autonomously targeting the initial ignition of the fire and suppressing it before it starts to increase in intensity and range. This is achievable with the use of various materials and sensors including flame sensors, dc motors and water pump. As a result, robots are used instead of human resources in handling fires and therefore can lead to lesser casualties.

Earthquake is the most dangerous natural disaster in the whole era of human being life. Scientist efforts for predicting earthquake have no prolific result, so far. The earth complexity and geology structures are the main obstacles of these efforts. The importance of time at the occurrence of the earthquake has resulted in using powerful systems for real-time alarming and therefore lessening the casualties of the earthquake.
The present work is concerned on designing earthquake detection with notification system. With the advancement of technology, the system is able to detect ground accelerations at P-wave using an ADXL345 accelerometer then comparing the results based on the Richter Scale thus the magnitude of an earthquake can be identified. The researchers make use of an application called Blynk in which the monitoring and notification takes place.
Nowadays, almost all people use internet thus the researchers make use of this advantage in order to provide notification system in times of natural disasters. In this paper, we evaluated the use of one accelerometer as detection devices and collected both human and simulated earthquake data using the smartphones. In doing so, the researchers conducted several tests ensuring that the sensor is reliable and can detect various ground accelerations. Implementation occurs on to which it is proved that the system only detect vibrations underground disregarding the man-made and other vibrations.

The main purpose of this paper is to design an operational amplifier that satisfies the certain specifications. A single-stage operational amplifier using a 741 op amp. The design is analyzed theoretically, by simulation through Multisim, by hand calculations and actual testing of the circuit. The group encounter problems in making the final circuit because some of the specification was hard to meet because of low gain and high input current given to them but still the group met all the specifications.

Burglar Alarm System with SMS Notification is a home-based security system. Two different control system was combined for its practicality, to mention: an alarm and a notification system. The project is limited to a vault located at a close room. With the capability to alarm the possible intruder, it can also notify the home owner about the intrusion. Through the application of previous engineering courses and engineering skills, a research and a project was made for the execution of the mentioned control system which is a clear example of a closed loop system. Through the use of advanced technology, to mention: GSM Module, Arduino, sensors, mobile phone and other components, the circuit was constructed. Also, through circuit analysis and mathematical methods, data was gathered for the accuracy of the operation for the project. With advanced coding skills, the group simulated the operation and passed information through radio network (GSM). With these, a clear and clean passage of information was achieved and an alert/notificaton was sent. An alarm system was properly made, leading to a successful flow of operaton.
