Best communication projects for engineering students

“The single biggest problem in communication is the illusion that it has taken place”
-George Bernard Shaw

Well, this won’t concern the electronic devices since their communication happens seamlessly in an efficient manner. The entire operation of such electronic devices depends purely on how efficient their communication happens internally.

From the smallest devices like the smart watches to the industry advanced robots, each device uses various communication channels to function efficiently. And with the advancement of technologies, the way these devices communicate internally also has seen some great improvements.



First things first, so how does the communication process happens in these devices?

Any electronic device needs three essential elements to carryout effective communication:

  • Transmitter
  • Communication channel (medium)
  • Receiver

A particular communication system is either an analog communication or a digital communication at a time. For example, the communication happens for TV transmission is analog and the communication system for any device that is connected to internet happens via digital medium.
So, how exactly the data is being transferred within these electronic devices?
The data is being transmitted between the transmitter and receiver in two ways,

  1. Serial Communication: This is where the data is transferred one bit at a time through a medium
  2. Parallel Communication: This is where the data is transferred as blocks (8-bit) like Bytes through a medium

With rapid technological advancements, now we have a lot of wireless means of communications. The important ones among them are:

  1. Bluetooth Communication
  2. WiFi Communication
  3. Radio Frequency (RF) Communication
  4. GSM Communication
  5. Dual Tone Multiple Frequency (DTMF) Communication

Being an engineering student, you need to learn and get skilled in these communication technologies as all the devices that we see today use some kind of communication to transfer the data. As the technologies around us are developing at rapid rate, learning the theoretical concepts behind such communication mediums alone will not be enough.

You need to build a lot of projects to understand how the communication system happens internally in the electronic devices. So, here I am suggesting some of the communication projects specific to various domains which you can build to get skilled.

1. Bluetooth based communication projects:

Bluetooth is a technology that achieves high speeds of data transfer and can operate relatively with lesser power. And because of the flexibility that bluetooth offers, it can be connected to any mobile phone or computer and it very easy to integrate this onto any system. Bluetooth supports frequency band of 2.45GHz and can send data at 721 KBPS. But the only constraint with this communication medium is that it can only transfer the data over a shorter distance, generally upto 10 meters.

Here are some bluetooth based communication projects that you can do,

  1. Bluetooth robotics: Through this project you will develop a robot that can be controlled by your smart phone using an Android App. View more details
  2. Voice controlled robot: Through this project you will develop a robot that can be controlled by your smart phone using speech recognition technology. View more details
  3. Home automation system: Through this project you will develop an electronic device that can be used to control all the home appliances using an bluetooth Android App. View more details
  4. Robotic Arm: Through this project you will develop a robotic arm that will have 3 degrees of freedom and can be controlled using an Android App. View more details
  5. Self-balancing robot

2. WiFi based communication projects:

Smart Irrigation System using IoT Project for Engineering Students

WiFi or Wireless LAN is the most widely used digital means of wireless communication. As almost all the electronic devices that we use today are connected to internet 24x7, WiFi plays are major role in facilitating the data transfer. Also with the advancement of technologies in the recent past, now it is possible for any device (not only mobile phones & computers) to connect to internet through WiFi. Since the devices can be connected to internet through WiFi from any part of the world, it gives a stronger medium of communication for advancing technologies like IoT, Robotics etc.

Here are some WiFi based communication projects that you can do:

  1. Weather monitoring system using IOT: Through this project you will develop an electronic device that will record the temperature/humidity differences in the environment and send it to cloud for storage and analysis. View more details
  2. Smart irrigation system using IOT: Through this project you will develop an electronic device that will switch ON the water pump whenever the moisture level in the soil drops below a threshold and send the data to cloud for storage and analysis. View more details
  3. Smart water monitoring system using IOT: Through this project you will develop an electronic device that will monitor the flow of water through the pipe and send the data to cloud for storage and analysis. View more details
  4. Automated street lighting system using IOT: Through this project you will develop an electronic device that will switch ON the street light whenever the intensity of sunlight drops below a threshold and send the data to cloud for storage and analysis. View more details
  5. Smart building system using IOT: Through this project you will develop an electronic device that can be used to control all the home appliances autonomously whenever there is a human presence inside a room and send the data to cloud for storage and analysis. View more details
  6. WiFi controlled robot: Through this project you will build a robot that will be connected to your PC through WiFi and can be controlled by sending commands through a html page. View more details

3. GSM based communication projects:

GSM stands for Global Systems for Mobile Communications. With the prices of smartphone coming down, most of the people have their own phones and uses GSM technology to communicate between each other. GSM is capable of monitoring and controlling several devices remotely irrespective of distance limitations. The GSM module comes with an 8-bit microcontroller that seamlessly transfers the data between devices. Building projects on GSM technology is an effective way to understand the operation of this communication medium.

Here are some GSM based communication projects that you can build,

  1. Smart energy meter using GSM: Through this project you will develop an electronic device that will record the energy consumed by taking readings from the energy meter and update the user via sms. View more details
  2. GPS & GSM based tracker: Through this project you will develop an electronic device that will track the position of the system and update user the GPS coordinates realtime via sms. View more details
  3. Railway track security system using GSM
  4. Disaster intimation system using GSM
  5. GSM based railway gate crossing control

4. Radio Frequency (RF) based communication projects:

Radio frequency interface is being used instead of infrared (IR) to avoid the drawbacks of using infrared mode of communication. RF has a longer range and uses an RF transmitter & RF receiver to create the communication medium. As much as 15 devices can be controlled using one RF interface. RFID is one such application which uses radio-frequency electromagnetic fields to transfer information from RFID tag to RFID reader for identification purposes. From various industrial purposes to tracking activities, RFID provides an innovative way of communication medium.

Here are some RF based communication projects which you can develop,

  1. RFID based authentication system: Through this project you will develop an electronic device that will authenticate entry of only the registered user. View more details
  2. RFID based attendance system: Through this project you will develop an electronic device that will RFID based authentication system to mark the attendance of candidates. View more details
  3. RFID based passport identification
  4. Navigating robot using RFID
  5. RFID based device control & authentication
