Sensor Based Project Ideas for
Final Year Engineering Students
 Sensors are backbone of plant automation and robotics.
 Interfacing their output to the firmware is one of the important areas in
industrial applications.
 Sensors such as temperature, gas, humidity, IR, ultrasonic laser, PIR etc.
are widely used in the industries.
 Details about few sensor based projects

 A water level controlling mechanism is developed which senses the water level
in the tank without any contact with the tank and accordingly controls the
pump to fill water into the tank.
 Here ultrasonic sensors are used to sense the water level in the tank.
 The ultrasonic sensor senses the liquid level in the water tank and feeds this
information to the microcontroller.
 the microcontroller accordingly controls the switching of the relay switch,
which is a combination of a transistor and a MOSFET in this case.
 The relay is accordingly controlled to switch on the load in case the water level
is less or switch off the load incase the water level is more.

 This system uses a TV remote as a cordless mouse to perform operations on a
computer.
 The TV remote works on the principle of IR communication and the commands
are send to the computer through a control unit.
 Here the commands are sent from a TV remote in form of modulated IR rays.
 These rays are received by the IR receiver and converted to electrical signals
which are given to the microcontroller.
 The microcontroller converts these signals to binary commands and sends
these commands in serial form to the computer through a level shifter IC.

 Here a device is developed which produces IR rays which can block the rays
from the TV remote.
 The frequency of the IR light is same as the frequency of IR light by the TV
remote.
 This can be placed at the TV receiver such that the rays received by the
remote are superimposed by the IR rays emitted by this device.
 Here a timer powered by a battery is used to produce pulses at frequency
equal to the remote output signal frequency.
 It provides power to the IR diode and accordingly the IR diode emits IR rays at
that frequency.

 Rash driving is one of major reasons for road accidents.
 This is achieved by monitoring the speed of the vehicles and accordingly
generates a warning when the speed of the vehicle increases.
 Here a speed checker system is designed where time taken by the vehicle to
travel from spot on the highway to another is measured and the speed of the
vehicle is accordingly calculated.
 Output from both the timers drive a NAND gate which in turn drives another
timer to trigger a buzzer in case of the speed going more than the set limit.
 Incase the timing count is less than the set time limit, the speed is known to be
exceeded and correspondingly a buzzer starts ringing to give the indication.

 Ultrasonic sensor can be used to measure distance of any object from a
certain position.
 The sensor emits ultrasonic waves which are reflected back by the
object.
 The time taken by the waves to travel back and forth is calculated and
multiplied with velocity of sound to get the distance measurement.

 This system is used as a way to manage the consumption of energy in an
optimal way.
 It defines an easy way to save energy by controlling the switching of loads
in a room only on the basis of the number of persons entering the room.
 It uses IR sensors to sense the persons entering and leaving the room and
accordingly the control unit controls the switching of the load.

 The exhaust fans used at homes are used only to expel out hot air from the
room.
 Induction motors which consist of a main winding which gets the mains
supply directly and an auxiliary winding which gets the main supply through a
capacitor.
 By interchanging the supply between the two windings, the windings can be
interchanged and the direction of the motor can be changed.
 The commands for the desired direction are given by a TV remote and
accordingly the motor is rotated in desired direction.

 The major advantage of using LEDs as street lamps are their intensity can be
controlled by controlling the power supply to the LEDs.
 By sensing the arrival of vehicles, the LED street lights can be made to be
switched on only at the time when the vehicle passes through it.
 This is by using an array of LEDs to represent the street lights and pair of IR
sensors is used to sense the number of vehicles on the way.

 This system defines another way to optimize the use of energy and also to
overcome the problem of traffic jams.
 By sensing the number of vehicles on each side of a junction, the time for
which red light of the traffic signal glows can be controlled accordingly.
 This project achieves this by using LEDs as the traffic lights for each side of
the junction and using IR sensors for each side to sense the number of
vehicles.
