Locking and Alarm System using a two-step Security along with GSM Modeling

Detachable, reusable and cost-efficient lock system for existing safes using a two-step security along with gsm modeling

Even though in today’s market there are innumerable digital locks and safes available it is almost hackable plus not everyone can afford it. Our main objective of this project is to model a locking and alarm system which can be attached to any sort of the existing traditional locking mechanisms.

It will be developed along with keeping in mind that not all traditional systems can be replaced overnight. But to make them more secure a fuss-free kit can be made which will be useful for both domestic and business purposes.

Even though today’s market has innumerable digital locking systems, not all the traditional locks and safes can be replaced overnight. To solve this problem we propose a system where the modern tech can be used on the traditional method at a low cost.

Here we will use a two-level security system to make it more reliable. The system can also be further expanded by connecting its alarm signals to gsm sims.

This kit can be used for both domestic and business purposes

The main aim is to model this kit in a way that even a layman can use it for his own benefit.

GSM Based Smart City garbage Bin Monitoring System

This is Smart garbage Bin Monitoring System, In this Project, we are monitoring garbage of the dustbin, Once the garbage bin is filled we can see the status indication of the LED. There is an IR sensor in the garbage bin. In the same way, we also get the alert message is saying that the garbage bin is filled.

Here we are using GSM Modem, which is going to use to send an alert message saying that the particular garbage bin is filled and the indication is indicated there with Green & Red indications. If it is Green- The garbage bin is empty, If it is Red – The garbage bin is full.

Basically here the Arduino board is playing a major role in sending the commands to the GSM Modem saying that when to send the message. This Aurdino board is receiving input from IR sensors saying that what is the garbage whether it is full or empty.

When this gives the digital input to the Arduino, this Arduino will send the output signal to the status indication entities and also it sends the output signal to the GSM modem saying that send the message to the particular number saying that garbage is cleaned.

This is a very advanced project rather than IOT, in IOT there is lack of internet access but here we are using GSM. This GSM one message send to the Municipal Office and another message will send to Cleaning Section.

Density based traffic control system using IR sensors


The main aim of developing this Density-based traffic control system project is to provide real-time traffic signaling system in the city to reduce traffic jam.

In this project we are using IR sensors, Sound Sensors, Aurdino Omega to monitor the 4-way traffic density. Each Line has 3 IR sensors, IR sensor is basically a sensor which can detect the obstacle, basically, it works on the proximity principle, It has an IR transmitter and IR Receiver, where IR transmitter sends IR Light where it sees any obstacle the same transmitter light will be reflected back and falls on the Receiver LED. Based on the light reflection,  here we are monitoring the traffic density based on the number IR Sensors Sensed.

Drawbacks in the Present System:

Huge Traffic Jam on the roads with the existing system

Auto & Manual Mode in the present Traffic System

In the Auto Mode, Traffic lights are in the Timer Mode the Time will fix for 1 minute or 2 minutes, Manual Mode takes more human effort.

Proposed Development:

But here we have developed as per traffic density the signal system will work, It mainly works with the help of sensors, If one sensor sensing when the green light signal time is 3 seconds, If 2 sensors are sensing then it will on for 6 seconds, If 3 sensors are sensing then the Green light will on for 9 seconds.

Based on that we just make a priority for all the 4 sides, Moreover, in our project, we have made some complex algorithm that monitoring the traffic density based on the IR sensors, this is just too makes the Things faster in the morning times when we are going to offices.

Moreover, it has a sound detector which can detect the sound which can detect the outer sound, but this is only the program to take the digital input of the vehicle. When the ambulance comes then the sensors will give input to the microcontroller board. This microcontroller board it makes the priority for this line of 9 seconds.

In this Prototype Kit, we have not used DSP Kit in the project. But the sensor if we connected to the DSP Kit if we connect to the microcontroller then We can connect to the ambulance siren also.

This Project can be applied to the real-time city traffic light signaling system.

GSM and GPS based Smart File Security System


The main aim of this Smart File Security System project is to design and development of a certificate folder tracking system. The tracking devices are GSM and GPS modules. The GSM and GPS tracking system are one of the modern accurate tracking devices. Our design comprises with the Arduino MC that controls whole the system.

These devices are used to locate the particular location of the objects such as lost certificate folder, identification of lost keys and send their coordinates to the user through an SMS. GSM digitizes and compresses the data, then sends the data to a channel in its own time slot. It operates at 1800 MHz frequency band. GPS receiver collects the information to calculate the user’s exact location.

The tracking devices are used to locate particular objects using GPS (Global Positioning System).The design consists of GSM and GPS system to track the location of the object. By arranging this tracking device in the objects like folders, briefcase etc. the user could track their location from time to time. This makes the user find his belongings within less time.

The design is done in such a way that the system could be arranged in less space and accurate in tracking locations. As there is a GSM slot in the design, the user could get coordinates of the object from time to time through SMS. The design consists of an alert system to find an object by the sound.

The size of the microcontroller can be decreased, and it can be arranged in the small objects. As this project is based on a microcontroller, GSM, and GPS. This project is developed with low cost by integrating GSM and GPS.

The system consists of different modules which are linked wirelessly with GSM modules. Cost effective SMS service of GSM network is used for transfer of data between the modules. This service provides the information about the location of the place, of the certificate folder.

Working operation of project

In this project we are using Arduino nano as microcontroller unit for reading and sending the data, We have GPS NEO 6M for getting the current location of module and this is interfaced to Arduino nano to pin 2 and pin 3, GPS NEO 6M will send the serial data in NEMA format to Arduino nano, and Arduino nano will take longitude and altitude values, whenever the GSM modem receives the message it is sent to Arduino nano and this will send the GPS location to sender (file owner).

GSM modem will be connected to Arduino nano to pin 0 and pin 1 RX and TX, Arduino nano and GSM SIM 800 and Arduino nano will communicate each other with AT Commands, GSM modem will have SIM card. We have small piezoelectric buzzer integrated into the file for easy identification of file with the sound indication.


• Certificate files.
• Property document files
• Other Important log data files etc…


This project is very useful as compared to existing file folders system which can track the file with small SMS with help of GPS system. This project can be further modified to IOT for more easy access with android application.

  • Whole system integration is controlled through Application installed in Android where controlling the device will get very easy to the user.
  • Weighing the luggage will become easy.
  • The carry of luggage is changed with motorized wheels.

Future Scope:

  • The application should be more dynamic and it should show the live feed of the movement of the luggage which updates every time the luggage is in movement. The tracking could be taken online using the cloud technology.
  • The introduction of Digital Locks into the luggage will help the user secure the contents of the luggage with the help of dynamic encryption algorithms and techniques which will safeguard any Machine to Machine Communication.
  • It comes with GSM module which helps us to triangulate its location when GPS is failed to retrieve the data.
  • Get the status of the flights, regulations using app and pack accordingly.


  • The limitations of the traditional luggage will overcome with Smart Luggage. The market is still new and has potential to accept the new face of luggage.
  • Know the weight of your Luggage at any time and pack accordingly.

Department Announcement System ECE Project Abstract


In most of the institutes, announcements are coming under the major problem. A universal announcement by speakers is mostly deployed in most of the institutes, but there are cases when the announcement needs to be done for a particular classroom or for a particular person.

In that case, such a universal system will not be helpful. One resolution of this problem most of the institutes adopt is deploying one universal system and a separate system for each room and then place people to handle the entire control system.

Though this resolves many issues, it increases the cost of the entire control unit when you have to be dependent on human resources. Automation is one of the most thriving of today’s technology through which many organizations are cutting costs on Human Resources and utilizing human resources in more innovative and productive works.

So here for this issue also we have come up with automating the entire process of announcement where a pre-recorded voice will be played for every announcement in the institutes.
