1) RF Based Load Automation for smart home

Nowadays, modern houses and organisations are gradually shifting from conventional control system to centralised control system. This centralised control system make use of RF remote control to operate the equipment.

We can build this centralised control system by use of RF Transmitter, Receiver, micro controller, Encoder, Decoder, Switches and relays. This project costs near around 3000Rs – 4000Rs.

2)   Home Automation using TV Remote

This project looks very interesting and impressive as it involves home automation using our TV remote control. Infrared signals transmitted by remote control will get captured by sensor interfaced to control system. All the loads which you want to automate are connected to control system through relays.

Future scope of this project: You can enhance this project based on radio signal instead of Infrared signal of remote control. This will increase operating range so that you can operate equipment which are far away.

3) Recognition of Vehicle Number Plate using MATLAB

This is also one interesting project for Instrumentation Engineering students. In this project we are using just MATLAB so this project is also cost effective.

Here we capture the image of Vehicle number plate and by use of Image processing in MATLAb we can extract the data from that image. MATLAB will recognise the numbers from number plate and will show it as output.

4) Temperature control system using LabVIEW and Arduino

In this project we make use of LabVIEW and Arduino. To measure the temperature we can use any temperature sensor like thermistor, RTD, etc. We connect these sensors to analog pins of Arduino which will be interfaced to LabVIEW.

We can set our desired logics in LabVIEW to operate the heating elements. These heating elements are connected to arduino through relayes.

List of Final Year Projects for Instrumentation Engineering

Hello, friends. It is very important to choose a good project in your final year of engineering. Your project should be attractive, innovative and more important is its output. If you successfully built a project and obtain its output you will definitely get good grades. So always choose a project for your final year which will be implementable (means you can get all its hardware), and you will be able to get its output.

Final Year Engineering Projects

Following is a list of Final year engineering projects for Instrumentation and Control Engineering students.

1) Machine Vision Based Object Sorting

This project is based on Machine vision. You can use a digital camera of your mobile or a separate camera for detecting objects. A conveyor can be used to move objects from one place to other. Whenever a defective product or unwanted product is passed over a particular point a camera will detect that product and will be sorted out. You have to use LabVIEW or Matlab for image processing.

2) Temperature Control System using PLC

PLC is one of the core subjects in Instrumentation and Control Engineering. So it will be impressive if you use PLC in your project. To built a Temperature Control System using PLC you can use RTD or Thermistor and a Heater. Whenever temperature rise above the predefined level a coolant (water) can be circulated surrounding the tank. When the temperature goes below set point a heater will get automatically on. You can use a PID controller for better controlling action than on-off control. This is really a good final project for  Instrumentation and control Engineering students.

3) Automatic Bottle filling project using PLC

This is also a good project for the final year. Its hardware is attractive and use of PLC in the project will impress your external. In this project, you can use a conveyor for bottle (cups) passing. IR sensor will detect the presence of bottle. At the same time, it will stop the conveyor. By generating a timer in PLC a Solenoid valve will start filling bottle. When the timer is completed solenoid valve will be closed and conveyor will get the start.

4) Automatic Irrigation System

This is an interesting project and involves measurement of soil moisture using Hygrometer. A hygrometer is an easily available sensor or eBay or amazon.  Whenever soil moisture decreases a pump will get start and water will wet soil. Thus no need of human for watering plants or farm. You can use and Arduino for analog reading and its digital output pins will operate pump on and off.

5) Home automation using PLC

In this project, we can control home appliances like a fan, Bulb, etc. using PLC. You can make use of Relays to connect home appliances with PLC.

6)PC Based Wireless transmission of process parameters

This is also a good final year project for Instrumentation and Control engineering students. In this project, you can transfer readings of process parameters like temperature, flow, pressure, etc. from one PC to other wireless. For this, you can use ZigBee.

7) Auctioneering Control System using LabVIEW

Auctioneering Control System
Auctioneering Control System

This is really a core instrumentation project. In this project, you are going to control the temperature of the system using auctioneering control system. It means measuring parameters at different location and control action will be taken based on the most appropriate reading. Same hardware as that of Temperature control system using PLC discussed above can be used. Except for PLC you can use LabVIEW and Arduino.

Theory

In this mini project, we have used PIC microcontroller and a four digit seven segment display is interfaced with it. For sensing the surrounding temperature we have used a temperature sensing IC i.e. LM35. You can use a voltmeter to crosscheck whether the indicator giving correct output or not. The output of the temperature in terms of volts will be in the range of mV.

Working of LM35

LM35 is an integrated temperature sensor. It produces an output voltage proportional to the temperature. The advantage of using LM35 is that it does not require any external calibration technique and it has an accuracy of ±0.4 degree Celsius at room temperature. It draws the only 60µA from supply and possesses low self-heating. Thus the chances of error get minimized.

How to Make a Constant Current Source using LM317

Hi friends, today we will see how to make a constant current source using an LM317 regulator and a single DC supply. You can vary the magnitude of current using the formula given below.

Circuit diagram

The following figure shows the circuit diagram of constant current generator mini project.

Constant current source
Constant current source

Components required

  • LM317 voltage regulator
  • 12V DC power supply (9V can also be used)
  • Resistor (depends on your requirement)

Working principle of constant current source circuit

As shown in the figure, constant current source produces a 20mA current across its output. The voltage across output is lower than DC supply voltage by 3V. In this case, we have used 12V DC supply, therefore, we will get 20mA current with 9V across its output. If you use 9V DC supply you will get 6V across its output terminals.

LM317-pinout-diagram
LM317-pinout-diagram

LM317 is a linear voltage regulator IC having following specifications:

Attribute Value
Vout range 1.25 V – 37 V
Operation ambient temperature 0 °C – 125 °C
Vin – Vout difference 3 V – 40 V
Minimum Load Current 3.5 mA typical, 12 mA maximum
Output Imax 1.5 A (with proper heat sinking)

LM317 can be used as a current regulator by replacing its low side resistor of the divider with the load itself. In our case, suppose we are using DC motor as a load. We will get 20mA current flowing through DC motor. The formula for output current is given by,

I = Vref / R = 1.25 /62 = 20mA

1.25V is the reference voltage of the LM317 regulator.

You can download LM317 datasheets from the following links:

  • LM317 Texas Instruments
  • LM317 ON Semiconductor
  • LM317 STMicroelectronics

  • NPN Transistor (TIP41)
  • PNP Transistor (TIP42)
  • Resistors and capacitors
  • Inductor of 1µH
  • Variable resistor (potentiometer) of 50K?

Circuit diagram

Following diagram shows circuit for DC to AC voltage converter using NE 555 timer IC:

12V DC to 120V AC Converter
12V DC to 120V AC Converter

Description and working of DC to AC converter

Above circuit can be used for a range of +5V to +15V DC voltage. This DC voltage is applied to the NE555 timer IC. NE555 produces frequency proportional to the input voltage. At the output terminal, we have used two transistors. One is NPN and other is PNP. These two transistors are used for driving transformer coil. An inductor of 1µH is used in series with the 2200µF capacitor.

Note:

  • You can also get output voltage between 120V to 230V AC at 50-60Hz.
  • The output voltage depends on the step up transformer used in the circuit.
  • You can also use a similar transistor instead of TIP41 and TIP42.

You can use this as your second or third year engineering project. This is a simple mini project using IC555. It is easy to build and all components used in the circuit are easily available.

This mini project generates a sound like police siren using astable multivibrator circuit of NE555 timer IC. You can make this project as your first or second year engineering mini project. This is one of the simple but useful mini projects and all components used in the circuit are easily available.

Components required

  • Two NE555 timer ICs
  • Resistors and Capacitors as shown in circuit diagram of police siren alarm
  • Speaker (64 ohms, 560mW)
  • 12 V DC power supply

Circuit Diagram

Working of Police Siren Alarm Circuit

As discussed earlier this circuit uses two NE555 timer ICs which are connected as an astable multivibrator. This circuit can be operated on the 12V dc power supply (you can also use 9V battery). To generate a siren sound we have used a speaker having specification as 64 ohms and 560 mW.

In this circuit, IC1 is used as slow astable multivibrator which works at 20Hz and having duty cycle as 50%. IC2 is fast astable multivibrator and having high frequency than IC1 nearly equal to 600Hz. These frequencies of IC1 and IC2 depend on values of resistors and capacitors used in the circuit.

Because of two different frequencies of IC555 and output of first is connected to the second it produces sound like a police siren.

Rain Detector with Alarm Circuit: Electronics Project

Hi friends, today we are going to make a simple mini project which is rain detector with alarm. This mini project generates sound using speaker whenever rain starts. The circuit diagram of this mini project is very simple and you can make this project as your first or second year engineering project for electronics and electrical students.

Components required

  • Resistor: 10K, 330K
  • Transistor: BC548, BC558 (other equivalent transistors can also be used)
  • Speaker
  • 3V DC supply (you can also use two 1.5V normally used cells in series)
  • Probe (it is nothing but a set of two open ended wires)

Circuit diagram

Rain Detector with Alarm circuit

Working Principle of Rain Detector

The working of this rain detector mini project is very simple. In this mini project, we are using a probe placed in a small plastic container. Whenever raining starts water get collected in that plastic container. As water is the conductor of electricity the contact between two open ended wires (probes) takes place and current start flowing towards the base of NPN transistor BC548. Here collector of BC548 NPN transistor is connected to the base of BC558 PNP transistor. Therefore when NPN starts conducting PNP also starts conducting.

Due to conduction of PNP transistor current starts flowing through the speaker and it generates an alarm. As in this mini-project, we have used a resistor and capacitor in series it causes the first transistor to turn on and off continuously till there is rain water present in the plastic container. This on and off period depends on the values of the capacitor, resistor and inductive coil of the speaker. Because of capacitor charging and discharging period it continuous to turn on and off continuously. This on and off condition of the transistor causes to generate a siren-like alarm from the speaker.
