In the recent years, huge improvements have been noticed in the world of technology and computerized systems. In the biomedical world, the equipment should features of user-friendly operation, portability, high level of safety and lower cost. These biomedical equipment ranges from medical diagnosis and treatments to provide supports for disable people for their daily movements. In Bangladesh, to ensure better healthcare, we are looking forward to getting the best equipment with the least cost. The needs of my country basically motivate me in aiming this project. This project has two parts, in the first part, the effort has made to build a simple, less expensive, graphic based heart beat rate monitor system which can be used for medical diagnosis. In the second part, an object detector system has been developed to help physically handicapped persons to detect object in front of them. The Object detector system can be modified for the vehicles safety as well as to minimize the risk at road accidents during travelling through foggy condition.

3. Building of Heart Beat Rate Monitor
& Object Detector
So Let’s have a look at my
project.

4. Building of Heart Beat Rate Monitor
& Object Detector
Why I choose this project?
 Middle class and poor (Under poverty).
 Not capable of taking better health care.
As a result, Life becomes harder for an old man.
Most of the people of our country:

5. So What is the Solution?
In Bangladesh to ensure better healthcare:
 we are looking forward to getting the best equipment with the least cost.
The needs of my country motivate me in
aiming this project:
 Basically my desire was to make a biomedical equipment that can do
medical diagnosis and treatments as well as provide supports for disable
people for their daily movements.

8. Building of Heart Beat Rate Monitor
Outline:
 Why I choose this project?
 How to Measure Heart rate?
 Challenges We faced!
 Hardware System Flow
 A Short Overview
 How Signal Drives into Circuit through INA 128?
 Pre-Processing
 Software we used ?
 Design Requirements
 Software Development Cycle
 Future Scope

9. How to Measure Heart rate?
• Stethoscope is inaccurate
• Electrocardiogram is
costly
• Not user friendly
2 Available Measurement System

10. Challenges We faced!
So, The effort has made to build :
a simple
less expensive
graphic based
heart beat rate monitor system which can be
used for medical diagnosis.

18. Design Requirements
• Instrumentation amplifier INA128
• 16x4 characters Liquid crystal display
• Trainer board
• 8 ohms mini speaker
• LED
• Breadboard
• Resistors :
• Capacitors:

20. Algorithm
• Initialization
• Step 1: Loading of Liquid Crystal Library and object creation of Liquid Crystal Display with input pins.
• Step 2: setting the external variable pin signal, time an frequency.
• Step 3: setting the internal variable pin start time, period, and last input.
• Step 4: Setting up LCD main module for displaying heart rate.
• Calculation
• Step 1:
• period = time – start time;
• start time = time;
• death = time;
•
• Step 2:
• frequency = 60000/period;
•
•
• Decision
• if ((time - death) > 2000)
• print("dead! ");
• else
• print("alive! ");

22. Future Scope
•Noise Free
•Low Cost <5,000/= BDT.

Building of Object Detector
based on Arduino Development Board

24. Why This Project?
• The current trend in our society is to send age old
civilizations into an old home, because they are unable
to do their basic physical needs by themselves.
• As a result we want to invent a system that can work as
like as their helper.
• We want to show how consumer devices like object
detector system can be used here in order to their good
will.

25. Two significant facilities
1) For physically Handicapped specially for
Paralyzed, Blind and as well as Dumb persons.
2) For vehicles in typical smoke condition at winter
season

26. As an Eye of Blinds.

27. Like a torch light

28. Who Becomes Benefited?
For old and physically handicapped persons,
previously unable to walk without anyone’s help
or direction, now will be able to walk inside his
own room safely.

29. A typical old man
With no eye sight and
Can’t hear sounds
Paralyzed
Now they can easily be able to walk without
anyone’s help or direction.

30. Types of Notification
1) A vibrator: which will respond (vibrate) if the system
found any objects in front of it.
2) A Led: which will respond (blink) if the system found any
objects in front of it.
3) A speaker: which will respond (beep) if the system found
any objects in front of it.

31. To Drive Safe

32. From the previous Image
We can see that there is too much smoke in the
road.
It’s very difficult to see any vehicles standing or
running with more then 50 meters distance.
Possibility of road accident.

33. In a foggy winter morning
We know that, at winter season there is too much
smoke/due factor in the road. some times it
becomes more challenging for the drivers to
drive the bus/car or any vehicles specially at
winter night or early morning.
Now they can drive safely if system is installed
within their loving vehicles. Suddenly it can save
a lot of life.

34. configured with in BUS/CAR

35. Types of Notification
1) A speaker: which will respond (beep) if the system found
any objects in front of it.
2) 2) A LCD: which will show the calculated (meter) the
distance of the upcoming vehicles.
