PROCESSING SOFTWARE
Processing is a programming language, development environment, and online community.
Since 2001, Processing has promoted software literacy within the visual arts and visual literacy within technology.
Initially created to serve as a software sketchbook and to teach computer programming fundamentals within a visual
context, Processing evolved into a development tool for professionals. Today, there are tens of thousands of students,
artists, designers, researchers, and hobbyists who use Processing for learning, prototyping, and production.
SIGNIFICANCE OF HEART
The heart acts as a pump that circulates oxygen and nutrient carrying blood around the
body in order to keep it functioning. When the body is exerted the rate at which the heart beats will vary proportional to
the amount of effort being exerted. By detecting the voltage created by the beating of the heart, its rate can be easily
observed and used for a number of health purposes. Heart pounds to pump oxygen-rich blood to your muscles and to
carry cell waste products away from your muscles.

In this project, Wavecom Fastrack M1306B GSM Modem type is used. A GSM modem can be an
external device or a PC Card / PCMCIA Card. Typically, an external GSM modem is connected to a computer through
a serial cable or USB cable [14]. Like a GSM mobile phone, a GSM modem requires a SIM card from a wireless carrier
in order to operate.](https://image.slidesharecdn.com/abstract-180224072913/85/Heart-attact-detect-and-monitoring-system-via-arduino-2-320.jpg)
![The PC application first reads 600 consecutive samples sent by Arduino. Since the sampling rate was 5ms, it takes 3
sec to read the 6000 samples. The DC component (minima of 600 samples) is subtracted out from the samples. Next, the
range of the samples is computed. If the range is less than 50 counts, the received PPG waveform is very weak, and is
considered to be a noise. This could happen when no PPG signal is detected

Biomedical engineering (BME) combines the design and problem solving skill of engineering with
medical and biological sciences to improve patient’s health care and the quality of life of individuals. Cardiovascular
disease is one of the major causes of untimely deaths in world, heart beat readings are by far the only viable diagnostic
tool that could promote early detection of cardiac events[13].By using this we can measure ones heart rate through
PRESSURE SENSOR.

the mobile phone. . It is portable and cost effective. It is a very efficient system and very easy to handle and thus provides
great flexibility and serves as a great improvement over other conventional monitoring and alert systems

Heart attact detect and monitoring system via arduino.
- 1. Heart attack monitoring throw Sms with using GSM and automatic door opening with alarm ABSTRACT In this project we are implementing a heart beat monitoring and heart attack detection system using Internet of things. Now days we have an increased number of heart diseases including increased risk of heart attacks. The sensor is then interfaced t o a microcontroller that allows checking heart rate readings and transmitting them over internet. The user may set the high as well as low levels of heart beat limit. Thus concerned ones may monitor heart rate as well get an alert of heart attack to the patient immediately from anywhere and the person can be saved on time. INTRODUCTION In the new era of communication and technology, the explosive growth of electronic devices, smart phones and tablets which can be communicated physically or wirelessly has become the fundamental tool of daily life.The aim of IoT is to extend the benefits of Internet with remote control ability, data sharing, constant connectivity and so on. Using an pressure sensor which is always on and collecting data, all the devices would be tied to local and mobile networks. The term IoT, often called Internet of everything. Heart attack is the number one cause of death for both men and women in the INDIA. PROPOSED METHOD System description Current technology consists of optical and electrical monitors. The electrical method provides a bulky strap around one’s chest or hands. The optical method does not require the strap and can be used more conveniently than the electrical method. There are many constraints in producing a heart monitor. First, the technology used to measure the pulse has to be determined. A cost efficient way of measuring the pulse is the combination of a led and photo-sensor or pressure sensor. 2.1.ELECTRICAL METHOD The strap is heart rate monitor uses electrodes to monitor the electric volts that occur when your heart beats and pressure sensor sensing pressure in arms. The receiver detects this information from the electrodes via radio signal from the chest strap. The receiver, then, uses this information to determine your heart rate. Some monitors also include a "coded signal" which uses a special code in the radio signal, so that the receiver does not receive radio signals from other nearby transmitters and connect the gsm module. This is not always a huge problem, but can be annoying or corrupt your data. 2.2.OPTICAL METHOD Optical technique exploits the fact that tiny subcutaneous blood vessels (capillaries) in any patch of skin (fingertip, ear lobe, etc.) furnished with a good blood supply, alternately expand and contract in time with the heartbeat. An ordinary infrared LED/phototransistor and pressure sensor pair can sense this rhythmic change as small but detectable variations in skin contrast. This method uses both transmittance and reflectance principles. It is a non-invasive method of finding heart rate i.e. no attachments or insertions on the body. It is precise and cost effective. CIRCUIT DESCRIPTION The total circuit construct at infraret transmitter and receiver in human body.pressure sensor is detect the various pressure level in patient to doctor.pressure sensor fit to the wrist or arms to sense the various pressure levels. IR RECEIVER An infrared emitter is an LED made from gallium arsenide, which emits near-infrared energy at about 880nm. The infrared phototransistor acts as a transistor with the base voltage determined by the amount of light hitting the transistor. Hence it acts as a variable current source. Greater amount of IR light cause greater currents to flow through the collector-emitter leads.
