3.
Patients suffering from heart diseases need A heart attack
detection system to have A urgent treatment before its too late.

4.
 So, here is our idea to have heart attack detection system so that
the person gets to know that he is about to get a heart attack and
can take preventive measures .
 The goal is to provide early heart attack detection so that the
patient will be given medical attention within the first few critical
hours, Thus greatly improving his or her chance of survival.
 This device can be made by using smart sensor. It converts heart
beat into pulses and it can use the micro-controller wireless
transmitter-receiver which can be built in the form of buzzer.
when it detects the heart attack it sends signal to buzzer and
displayed in the display as emergency.

• TRANSFORMER:
It is a static device which converts one voltage level to another
voltage level without changing its frequency. So, in this we are
using step down transformer that is 12V.
• HEARTBEAT SENSOR:
Heart beat sensor is used to measure the pulse rate of heart in
digital output.LED is used to detect the heart rate. The normal
heart beat range is 78 BPM. This provides a direct output digital
signal .
• MICRO CONTROLLER:
It will keeps track of pulses given by sensor. It continuously counts
pulses and detects any irregularity in pulse count. In this we are
using ATMEGA328P AVR MC.
• LCD(liquid crystal display):
All the data can detected by sensor and give it to display.

7.
• ATMMEGA 328:
It is an 8bit microcontroller. It is an AVR based microcontroller. Its
built in internal memory is around 32KB. It had an ability to store the
data even when the electrical supplied is removed from its biasing
terminals.
•BUZZER:
It is used to alert the person supervising the heartbeat rate of
the patient and terms on the buzzer as soon as heart beat level
of the patient dose not fall with in the normal at.
• ENCODER:
It is an electronic device used to convert an analogue signal to
digital signal such as a BDC code .
• DECODER:
it is an electronic device that is used to convert digital signal
to an analogue signal .
•ANTENNA:
it is a specialized transducer that converts radio frequency
fields into alternating current or visevarsa
