Wireless Communication Projects for Engineering Students

Wireless communication is defined as sending the information from one point to another point or multiple points without using wires. Wireless communication allows a long range communication, whereas in other communications it is impossible to implement using wires. This communication is used in telecommunication industries and it uses some type of energy to transfer information without using wires over short & long distances. These technologies use radio waves using the radio for short and long distance radio communications. This communication is mainly used in mobile, fixed and portable devices that include PDAs, radio ,cell phones and the applications of wireless communication projects include garage door openers, GPS, wireless computer mice keyboards, satellite vision, headsets, broadcast television, etc.

Wireless Communication Projects

Wireless Communication Projects based ideas 2015

Wireless communication based projects mainly involve different types of wireless technologies such as GPS, Bluetooth, FID, Zigbee and GSM. For better understanding of these wireless communication technologies we have discussed with projects.

RFID based Ambulance Flashing Light with Beeper

This project is designed to provide a flashing light, which is commonly used in ambulances and emergency vehicles. These flashing lights are located at the top roof of the vehicle to clear the vehicles on the way and also to give an alert to the people to wait and permit it to pass smoothly. The proposed system uses a 8051 families microcontroller to give flashing light at the particular time intervals. A 12v lamp is driven by a power MOSFET in the mode of pulse width modulation. The duty cycle of the pulse width modulation has to be changed as per he type of application. In the future, this project can be developed by using the 230V lamp for better visibility.

Bluetooth based Garage Door Opening

The main concept of this project is to design a Bluetooth based garage door opening system with a unique password by an any android application. The owner can connect the Bluetooth device with the android application to the system. The proposed system uses a ATMEGA microcontroller to control the garage door open and close by entering the unique password.When the entered password is right, then the door will be open otherwise it will generate a buzzer sound. Further, this project can be enhanced by using an EEPROM so that the password can be changed by the authorized person.

DTMF based Load Control System

This load control system using dual tone multi frequency is used to switch any electrical loads. In various industries, agriculture fields and in the houses different loads are located in large areas so, controlling of loads is a difficult task. To overcome this problem, the proposed system is designed to control the loads remotely by using DTMF technology

A cell phone is connected to a DTMF decoder with this project from its audio o/p outlet for receiving tone instructions. The receiving cell phone codes are changed into digital instructions by using a DTMF Decoder which will recognize the frequency of the key and alter that frequency to its corresponding digital code which is then fed to a microcontroller. According to the instructions sent from the mobile user, the 8051 microcontroller will send indications through a buffer to activate the particular loads by switching the relays ON/OFF. These relays are triggered by a relay driver IC connected to the microcontroller.

In the future, this project can be developed by using a GSM modem, where the different electrical loads can be controlled by sending an SMS. This will remove the necessity of replying the call for the system to work.

Smart Card Technology based Security System

The main goal of this project is to design a security system using smart card technology to control a device or to access an area. This smart card technology is used in many organizations to access a secure area by using a valid smart card.

At present, human interference was compulsory to observe all these parameters, but using this project no human interference is required. Because this project uses a valid smart cards to operate devices.

Smart Card Technology based Security System Project Kit 

The smart card reader is interfaced to an 8051 family microcontroller. When the data is read from the smart card data on the microcontroller matches, then the message will display on the LCD that the smart card is authorized. A relay is used instantaneously to turn ON a lamp

If an unauthorized card is interleaved in the smart card reader, it displays the message on the LCD display that the card is not authorized and the lamp remains OFF representing that the person is not authorized to entrée the specific area or device. In the future, this project can be developed by adding GSM modem such that any effort of illegal access is made, then an SMS is sent to the concerned department.

Zigbee based Automatic Meter Reading System

The main concept of this project is to design an automatic energy meter reading system using Zigbee. This meter sends unit based pulses which are connected to an Opto coupler that calculates the pulses every time, then the led blinks. As per the ingesting it gives necessary interrupt signal to a micro controller.

Zigbee based Automatic Meter Reading System Project Kit 

The 8051 microcontroller receives the reading from the meter through an Opto-isolator and reading will be displayed on the LCD which is interfaced to the microcontroller. The energy meter’s reading is sent wirelessly to the user of the personal computer by a serial data transfer via an 2.4 GHz XBee module attached to the microcontroller.
