description: Heat waves could be fatal without a proper cooling system. Lakes could be a natural and environmentally friendly choice for cooling down outdoor areas. Due to the slow temperature fluctuations on large bodies of water, it cools down the surrounding areas during summer or during a heat wave. This study is conducted to develop a low-cost monitoring system to determine the effects of a lake on its surrounding areas. It also analyzes the difference between an area with a lake and another without, while testing the performance of the BME280 sensor in the process. The results show that due to evaporation, the temperature of location A (near the lake) is lower compared to location B, (Tokong Nanas Building). The Humidity of location B is higher than location A due to its more enclosed properties compared to location B. Lastly, the pressure of location B is lower than location A because of the higher humidity in location B.

Studying the Temperature and Humidity of the Environment to Determine the Best Location for the Swimming Pool with BME280 and ESP32
type: item
description: The typical daily pool moisture content amounts to approximately a quarter of an inch, with an accumulation of over two inches within a week. This phenomenon can be attributed to the elevation in temperature and humidity within the pool area, triggered by an increase in swimming activity. As more individuals engage in swimming, both the water temperature and the overall ambient temperature rise, thereby expediting the evaporation of pool water. One of the key determinants of water evaporation is its temperature, which varies between indoor and outdoor pools. This paper delves into an analysis of the ambient temperature and humidity to identify the optimal location for a swimming pool, leveraging the BME280, ESP32, and Favoriot dashboard platform. The findings illustrate that the utilization of the BME280 sensor can effectively establish the most suitable swimming pool condition based on environmental temperature and humidity. The data gathered suggests that indoor pools are a preferred choice, given their ability to shield against the erratic outdoor conditions, thereby ensuring a more consistent temperature.

Development of Vertical Axis Wind Turbine (VAWT) During Windy Season for the Rural Area in Langkawi
type: item
description: Wind energy is one of the clean energy sources. This project is carried out to take advantage of the windy season inland and along the coast of Langkawi. Wind energy is converted into electricity by driving a brushless generator motor to produce a Direct Current (DC) voltage of 12V. The output voltage from the DC motor will be stored in the battery before being fed to the inverter. These inverters are used to convert DC energy into Alternating Current (AC) output. The AC output can be increased by using a transformer up to 220 VAC. The voltage output from the inverter will be fed to the user to turn on electrical appliances at home. Electricity supply is very important nowadays because of the rapid development of technology. Some residents in rural areas do not get electricity from Tenaga National Berhad (TNB). This is because their place of residence is too far or isolated. To ensure they have a constant supply of electricity, a system called the Vertical Axis Wind Turbine (VAWT) has been designed. With this system, power supply troubleshooting can be improved to turn on electrical equipment such as lights, fans, ice boxes, and more. This system is developed by using wind energy which is one of the other methods to supply electricity. The results from the experiment show that as the wind speed increases, the output power from the DC motor will increase. The proposal uses specialized software and designs wind turbines that will be able to generate voltage and current.

Design and Implementation of Solar Tracking System Using LDR Sensor
type: item
description: Solar technology has been widely used nowadays because the source of sunlight can be converted into electricity and used by humans on the surface of the earth. The National Energy Policy (NEB) acknowledges the increase in oil prices in 2015 and the global electricity crisis adversely affecting Malaysia, which is solely dependent on oil. In general, when harvesting solar energy can be done, another challenge that will be faced is the inefficiency of solar panel arrays, and insufficient sunlight sources due to weather factors to generate more electricity. To solve this problem, another approach is to build an automatic system that consists of solar panel tracking, Light Dependent Resistors (LDRs), microcontrollers, and servo motors that are used to detect sunlight throughout the day to allow the system to generate maximum electricity. It was found that the voltage output from the solar panel detection approach is higher when compared to the horizontal method which is a fixed solar panel. Therefore, the output generated from the built system will be distributed to the rural population for daily use.

Analysis of Bite Force Measurement for Stomatognathic
type: item
description: An analysis examines the biting force with proposes measuring maximal voluntary bite forces associated with the chewing muscle's size. Bite forces must be reliable and accurate to be used clinically using a pressure force sensor. The cross-sectional area of a muscle determines the maximum force it can produce. The force exerted by the masticatory muscles during tooth occlusion can be up to ±700 N. The cross-sectional size of various jaw muscles, measured with a computed tomography scanner or magnetic resonance imaging (MRI), is widely associated with maximum bite force. It can be recorded to evaluate the function and effectiveness during the occlusion. Bite force has been used in dental research to measure the effectiveness of various dental operations. In stomatology, measuring bite force is critical, and choosing the suitable measurement method and apparatus is essential for accurate results. Results: Successfully aimed to design for efficient, reliably reproducible measure and to compare the results in a small population with obtained results revealed that males had a significantly higher bite force than females. Conclusions/Recommendations: This study is helpful for stroke patients for measuring the bite force after the rehabilitation activity.

Automatic Roof Cooling & Monitoring System
type: item
description: Recently, Industrial Revolution4.0(IR4.0) changes the landscape of industrial in Malaysia. The internet of things (IoT) is one out of nine technology-driven in IR 4.0 which requires internet as the fundamental for physical devices connection. Many companies have been transforming their products in a complex context such as the home automation system market. Unfortunately, not all users can afford to own this home automation system due to its high price. The home automation system is important because it can facilitate people and shorten the time to turn on and turn off the electrical appliances. Most home automation systems use manual ways as the medium in which this factor may hinder the benefits for users who prefer to turn on and turn off their electrical appliances in simpler and easier ways. To overcome such limitation, this paper proposes a development of home automation system via sensors and microcontroller to develop an automatic system in the building. The proposed system functionality was evaluated using real electrical appliances and it successfully worked with the use of sensors. The proposed system was developed at a low cost and it could be commercialized at an affordable price. Hence, this project could narrow the gap between all different stages of society (i.e.B40, M40 and T20 groups) in realizing the concept of IR4.0 in their daily lives.

type: item
description: An aging population is defined those aged above 65 years old. In 2020, it was estimated that the share of Malaysian population 65 years and above stood at seven percent. According to statement on July 2019 by Chief Statistician of Malaysia, 15 percent threshold made would be crossed in 2030. Recent estimates suggest that 8.5% of Malaysians over the age 60 having dementia, suffering from dementia and approximately yields population of 260,345 elderly with dementia. Many people with dementia have a prolonged disease trajectory, lasting years from diagnosis to death. Besides having trouble in remembering their personal details, they are also having problem on their medication management. The first problem to be addressed is the error of the caretaker giving medicine to patient. Medication errors are one of the most common health-related mistakes that have a negative effect on patients. Majority of the elderly are unable to manage themselves. More families are finding themselves unable to look after the elderly who are unable to manage themselves. Heart diseases remained the cause of death. The current heart rate monitor needs caretaker to visit every patient’s bed to make sure the heartbeat rate is normal. The results obtained from this medical robot shown on the Blynk applications.

description: Floods are natural phenomena that occur every year in Malaysia during the monsoon season which runs from November to January. Despite the fact that various steps have been taken, it appears to have remained unsolved. Here, the auto-drainage system to mitigate flash flood is proposed to improve the drainage system as it is one of the major reasons that caused the flood. This project is the first phase of the flash flood mitigation system where it provides crucial information such as water level in the drainage system, the plan and the preparation to the public as well as the local authorities. Auto-drainage system offers continuous monitoring on the water level in drainage system and allows water to divert into alternative drainage during critical times. There are 3 different levels of warning; low, medium and high. During low level, the water pump is in idle mode or in a safe zone. When the water reaches medium, the pump will start to divert the water into an alternative drainage system. At high level, the pump will continue to divert the water the notification to evacuate the area is despatched. The test run gives a positive result and fulfills all the objectives in effort to mitigate the flash flood.

Development of Dual Axis Solar Tracker with IoT Monitoring System
type: item
description: Despite the fact that solar energy is infinite, harvesting it is challenging owing to panel inefficiency. In many years, the old solar tracking method was normally set where the solar panel does not shift orientation towards the sun. Since the sun change its position with time, hence dynamic tracking system is needed. The aim of this project, to develop a dual solar tracker that can absorb more lights and real-time monitor its performances. By use of four light dependent resistor sensors, the sun position is tracked, and the microcontroller controls the servo motors to align the solar panel perpendicular to the sun. As a result, the dual solar axis tracker can capture 27.4% more solar power compared to fixed tilted axis. With an internet of things integrated to the proposed system, hence enable the real-time monitoring for the solar panel output performance through Blynk application and Thing speak website accessible from anywhere with stable internet connection.

Development of Sun Tracking Solar Panel Using Arduino
type: item
description: As we can already observe, the global warming has a heated influence on the world. Here the impact of global warming can be taken advantage of. For operating electrical appliances, we can use solar energy as electricity. The difficulty we can observe presently is most of the solar panel used only statically by a user. The solar panel cannot charge if the solar panel is located on the east and the sun is situated on the west. So, this project is termed the "Solar Tracker". The LDR was used to feel the strength of the light at 30 degrees or a total of 180 degrees each and relayed the data to Arduino. This Arduino compares the data and rotates a servo motor toward the sun in the proper direction. The servo motor rotates the solar panel according to the highest light intensity. The solar tracker project aims to improve output power from stationary solar tracking systems. A 180-degree rotation is detected by this sun tracking device resulting the amount of energy a solar panel can generate here is far more than when it can only generate in one direction. Indirectly, the cost of acquiring more solar panels will reduced. The technology also reduces the time it takes for customers to shift the solar panel's orientation to face the sun.
