Low Cost Electrical Engineering (EEE) Mini Projects with Videos

Projecting the cost to do your mini project is not very easy. Most of the engineering students predict it wrongly and end up compromising their mini project at the very end.

This is majorly because the cost to do an electrical mini project is not only dependant on the price of materials involved in it.

In order to calculate how much a mini project will cost to build, you need to consider a lot of parameters to predict it accurately.

So what are the factors that influences the cost of a electrical mini project?

1. Price of components: Any mini project that involves hardware needs a lot of components. The prices of these components varies from place to place. So you need to find out the exact materials needed to do your mini project and calculate the cost of it.
Tip: : Initially you can search online regarding the price of the components than going physically to shops to avoid any discrepancies.

2. Infrastructure charges: Most of the mini projects that you do, need various platform to carry out some functions. These vary from the laboratories that you need for testing to the workshops that you need to go for manufacturing components. Although your college has the laboratories, there are times where you need to go for some external facilities for advanced testing and it will incur some charges.

3. Kit damage: Since you are doing the project for the first time, without proper guidance you may end up damaging some components (like burning ICs, circuits etc.) And repairing these components is not easy and you may have to spend more money to get them replaced. Sometimes cost of your project becomes 2-3 times your initial prediction if you end up damaging the costly parts of your kit. (This is the biggest reason why cost goes up a lot in most cases as students don’t know how to use them and end up making wrong corrections that will burn some key components of the kit).
Tip: Have some prior precautions or get expert guidance before you start with your mini project.

4. Indirect cost: These are the cost that you need to consider other than the direct expenditure involved to do your mini project. It includes the transportation charges, shipping charges (if you order components online), purchasing reference materials etc.
Tip: In most cases, this will be around 20-25% of the total cost of your mini project. If you are in a tier 2 city, traveling to the nearest city to procure components itself might run into thousands of rupees.

By considering all these parameters, you will be able to project the cost to do your mini project effectively. This is truer for Electrical (EEE) mini projects, as there will be lot of components needed to do the mini project and good laboratories are required to carry out the testing.

So how can you build cost effective electrical (EEE) mini projects?

Getting the right kind of guidance / course tutorials for doing your electrical mini project will help you save a lot of money on replacement of damaged components, kits wastage, infrastructure charges etc. Also getting the expert assistance to build your electrical mini project will help you learn the concepts in an effective manner.

2. Automatic Solar Tracker:

Through this electrical mini project you will be developing a solar tracking device that can orient itself towards the direction of high intensity sunlight to effectively harness maximum solar power. This device uses a LDR (light dependant resistor) sensor to sense the sunlight intensity and send the data to the microcontroller. The microcontroller then controls the DC motor to move the solar panel and make it orient towards the direction where there is maximum sunlight. This particular solar tracking device in comparison with a conventional solar panel can produce 40% more energy.

3. Automated Street Lighting System using IOT:

The objective of this EEE mini project is to build an IoT based device that can replace the conventional street lights to achieve more energy efficiency. You will be needing a LDR (Light Dependent Resistor) sensor to detect the light intensity present at the environment and send the data to the microcontroller. You can then program the microcontroller to carry out specific set of actuations (like switching ON/OFF street lamp) based on the value that the sensor provides. Also all the data that is collected will be stored on the cloud for analytics purposes.

4. Home Automation System:

Through this electrical mini project you will be developing a smart device that can be used to control all the home appliances through an Android App. The device uses a bluetooth module to establish the connection with the Android App. Also the project uses an 8051 based microcontroller which will act as the brain of the system and controls the actuation process. You can also program the microcontroller to perform unique type of actuations like simultaneously switching ON the electrical appliances to make a pattern.

5. Smart Irrigation System using IOT:

The objective of this EEE mini project is to build an IOT based smart device that can facilitate the irrigation process with minimal loss of water and power. To achieve this, you will be using a soil moisture sensor that can detect the moisture level present in the soil and send the data to the microcontroller. You can then program the microcontroller to perform some actuations (switching On / Off of water pump) whenever the moisture level drops below a threshold value that you set. All the data will be sent to the cloud for storage and analytics purposes.

6. Smart Energy Meter using GSM:

Energy consumption monitoring is one of the important process that should be carried out at domestic & industrial locations. And through this electrical project you will develop a smart device that can record the energy consumption values from the energy meter and send the updates to the user as sms using GSM technology. You can also program the microcontroller to send the updates about energy consumptions at periodic intervals to the user from a remote location.

7. Smart Building using IOT & PIR:

Smart systems are being implemented on almost all the industries to save energy and achieve more efficient operations. Through this electrical mini project, you will develop an IoT based smart device that can sense the number of occupants within the room and switch on/ off the appliances in the room based on the activity inside. The data collected will also be sent to the cloud for data analysis purposes. You can also program the system to perform it as a theft monitoring system by connecting the device with a buzzer.

8. Smart Water Monitoring System using IOT:

Water management system is one of the complicated process to do in the real life scenario. Through this electrical mini project you will be able to build a smart device that can be used to efficiently manage the water consumption. The device will be equipped with a water flow sensor which can detect the flow of water through it and send the value of water consumed to the microcontroller. This value will be then sent to the cloud and stored for analysis purposes.

9. Smart Traffic Lighting System:

With the urbanisation on the rise, more and more vehicles are being added to the roads, increasing the traffic intensity at a very rapid rate. For such a rapid scenario, the conventional way of maintaining traffic will not be effective. The objective of this electrical mini project is to develop an energy efficient smart device that can control the traffic lights intelligently with the help of sensors. Also you will be developing a solar charger to power up this system and make it an energy efficient smart device. The microcontroller can be programmed to make this traffic lighting system work autonomously with no human interaction.

10. Health Monitoring Wearable Glove:

This particular electrical mini project is an application of the wearables technology. Through this project you will be developing a glove which a user can wear and use to detect the pulse rating of other persons. The wearable project uses a lilypad Arduino (miniature size Arduino) that is embedded on to the glove using a conductive thread along with the pulse sensor. A small display will also be embedded onto the glove to show the pulse values of the user.
