Undergraduate Projects

Undergraduates of faculty of Electrical Engineering, UTM are welcome to do their final year project or even take part into any competitions using the following projects titles under my supervision. The titles without a name@names are still available.

1)Wireless Wearable System for Cattle Health Monitoring
Wireless wearable system (WWS) for animal health monitoring requires many designs requirement. The main challenge in the design is to develop a system which can be place on cattle based on a wireless pulse sensor for cattle health monitoring. The WWS can be divided into four main parts as follows: power supply unit, pulse sensor, wireless communication module, and base station. The power supply unit will be based on alkaline batteries which can be recharged using a solar-powered battery charger. The whole power supply unit can be placed on a belt and put on a cow as a collar. Next, the design purpose of the pulse sensor is to provide the indication of the animal health state. The pulse sensor will consist of Light Dependent Resistor (LDR) and place on strategic spots such as on the ear. The wireless communication module will be based on Zigbee technology. Zigbee technology is an ideal choice for the wireless communication module because of its cost, ease of use, and low power consumption. Finally, a base station is actually a PC or laptop which will process, display, and store the data received by the Zigbee receiver. With the data obtained by the WWS unit, a farmer, rancher, or veterinarian can make detailed state-of-health analyses, enabling rapid treatment or early disease detection to prevent spread within or between herds.

2) Demonstration of PID controller on a Cup Warmer
The main purpose of research is to designs a cup warmer of liquid to set a temperature and automatically cools it down using PID controller. The main components involve are a pan heater, PIC16F684, AD595 thermocouple, AM401 voltage amplifier, and FSG15N1A force sensor. In this project, the concept of heater behaviour is learnt by constructing a simple TRIAC control circuit and programmed the PIC for full-power on/off control using a potentiometer as an input to the comparator circuitry of the microcontroller. Furthermore, a controller based on PID is integrated with the system to control the set-point temperature of the warmer. The PID controller’s components can be used independently or in combination, as required. Each component helps the controller drive to achieve and hold the desired set-point. The PID performance is evaluated based on the precision factor on the overshoot and on holding the set point. This project can be a helpful tool for control engineering student to understand the concept and application of PID controller in class.

3) Solar-Powered Property Guarding System (Amirah 'Aisyah binti Badrul Hisyam)
Sometimes we came under the restriction of protecting our valuable stuffs or properties which are in garages/sheds and distanced away from our living house, respectively. They all need protections against burglary or malicious vandalism by human or intrusive animals. This project proposes an alarm system based on a PIR sensor with solar power supply which requires no mains supply. The system employs four low-cost ICs and associated components. This system can be used for indoors application or outdoor application. Such indoor protection are for valuable stuff inside garages or sheds while outdoor application requires the system to strategically placed around fencing of a piece of land for instance. On top of that, the solar panel is equipped with a tracking solar panel system so that the 12 V power main-source maintains its orientation towards the sun under control of a timer. This project indeed is a peace of mind provider for us.

4)Study of Alternative Energy Harvesting: Solar Energy
Alternative energy is one of the hot topics today. This project will start with the following focuses: (a) Introduction to solar energy, (b) External Conditions that affect solar panels, (c) Building a solar poser battery charger, and (d) Building a “double wide” sun tracker. Initially, the experimental setup will involve two solar panels where experiments such as sunlight versus artificial light and determining the maximum power point of the solar power harvesting will be conducted. Furthermore, study will be conducted to delve into the reason why solar panels behave as they do by ways of observing the heat effect, the shading effect, and tilt angle effect on the solar power harvesting. To demonstrate the capability of the solar power system, a solar powered battery charger will be built along with “double wide” sun tracker to optimize the power harvesting. In the end of the project, the student will enhance the understanding of solar panel theory and technology.

5)Motorcycle Chain Oiler System Using PIC
Motorcycles are ubiquitous in South East Asia, many people keen on using motorcycles to commute between home and workplaces. They are relatively cheap and many places (workshop) can repair them. The spare parts are easy to find and even to replace. One of the most important parts of motorcycles is the chain. This part has to be taken care regularly in order to extend the life span. However, it is hard to make sure the chain is in good condition since South East Asia regions often receive a lot of rain. To solve this problem, a system based on PIC is proposed to automatically oil the chain so that it will always stay lubricated thus deterring from expedited wear and tear. It is expected that this project will help the motorcycles users to keep their safe riding and maintenance cost.

6)Illuminating Prayer Mat (HASAN AHMED MOHAMMED AL BAR)
The illuminating prayer mat is a convenient tool for Muslim travellers to perform the prayer. The mat consists of a tiny compass which is built around ATtiny84, which communicates with the compass module MOD1. The mat shows the right direction to pray by lighting up LED garlands sewn on the edge of the mat when facing Makkah. To determine the direction of Makkah, the user has to manually input the current city via the ‘city selection button’ while north will be determine by the tiny compass. The mat runs on a power supply unit which will be based on alkaline batteries which can be recharged using a solar-powered battery charger.

7)USB Data Acquisition Card
This data acquisition card for connection to the USB has eight digital outputs, eight digital inputs, two 10-bit analogue outputs and eight 10-bit analogue inputs for voltage swings of 0 to 5 V. The system’s core is a Microchip USB-savvy microcontroller type PIC18F4550 programmed in C. The circuit is built on a compact PCB and requires no external power supply. This project explains how USB actually works on a microcontroller and can be made to do something really useful at a very low cost. 

8) Study of Alternative Energy Harvesting: Wind Turbine
Alternative energy is one of the hot topics today. This project will start with identifying the types of wind turbines and building a three phase AC wind turbine out of a roof ventilator. The next step is to perform some experiments related to wind turbine which can be listed as follow: 
three phase rectification, 
understanding three-phase voltage output, 
smoothing the rectified DC output,  
wind speed, RPM, and power output,
the effect of magnetic coupling,
star versus delta windings, and 
Hands off braking.
In the end of the project, the student will enhance the understanding of wind turbine theory and technology.

9)Study of Alternative Energy Harvesting: Fuel Cell 
Fuel Cell is one of the interesting types of alternative energy harvesting. In this project three main contents will be covered which are fuel cell basics, fuel cell polarization states and efficiencies, and building a telematics car. In the end of the project, the fuel cell’s basic operation characteristics will be learnt. The inner workings and as well as applications for portable electronics/powering telematics vehicles will be addressed.
