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

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
How to Measure Heart rate?
•Stethoscope is inaccurate
•Electrocardiogram is costly •Not user friendly
2 Available Measurement System
Challenges We faced!
So, The effort has made to build :
a simpleless expensivegraphic based
heart beat rate monitor system which can be used for medical diagnosis.

Software we used ?
• Arduino IDE• Language C
Design Requirements
• Instrumentation amplifier INA128• 16x4 characters Liquid crystal display• Trainer board • 8 ohms mini speaker• LED• Breadboard
• Resistors :• Capacitors:

Processing of the Signal
Display outputSoftware Development
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! ");
Final Development
Future Scope
• Noise Free• Low Cost <5,000/= BDT. Device Invention.
Part 2Building of Object Detector
based on Arduino Development Board
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.
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
As an Eye of Blinds.
Like a torch light
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.
A typical old man
With no eye sight andCan’t hear soundsParalyzed
Now they can easily be able to walk without anyone’s help or direction.
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.
To Drive Safe
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.
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.
configured with in BUS/CAR
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.
Design Requirements
• Ultrasonic sensor• Arduino Mega 2560• Led• Speaker• Vibrator• LCD• Vero board• Connecting wires
Ultrasonic sensor
distance = (duration/2) / 29.1;
Software Development
Continuous input from ultrasonic
sensor
Sound processing and distance calculation

Algorithm
Initialization• Step 1: Loading of Liquid Crystal Library and object creation of Liquid Crystal
Display with input pins.• Step 2: setting the ultrasonic trig and echo pin• Step 3: Led pin initialization• Step 4: Setting up trig and echo pin.

Final Development
Please don’t hesitate to contact if any complication arises.
