![III.Working model:-
Health monitoring system with wireless alarm is a device
which will help the patient’s as well as the elderly people to
be properly taken care of. It is useful for people who are both
ill and also who are healthy. People who use this device will
able to be in peace knowing that they are perfectly safe. The
device will be in the form of a small wrist band which
contains the controller part and a small ring like extension
from the band containing the sensor which can be attached
to the upper part of index finger for detecting the heart beat.
It will be of great use to people as many, especially
elderly/patients will not be able to call for assistance in case
of emergency. So this device will solve the problem by
sensing the problem and then alerting the caretakers by
producing some alarm. Thus proper attention and assistance
can be given to the diseased person.
The hardware components used for the health monitoring
device with wireless alarm are :-
1. MSPEXP430G2 MICROCONTROLLER
2. TSL2561 PULSE OXIMETRY SENSOR
3. RF TRANSMITTER RECEIVER
The device is controlled by MSP430 microcontroller. Heart
beat is recorded using Pulse Oxymetry Sensor.This Pulse
Oxymetry Sensor gives the heart beat in the form of analog
signal.The Analog to Digital converter of MSP430 converts
the analog to digital.This is done by taking the average of the
highest crest and lowest trough of 200 analog wave readings
in order to get the accurate reading. This digital data is
processed by MSP430 to get the number of beats/minute. If
the heartbeat is too low or too high then the microcontroller
transmits the data to RF Receiver and a buzzer by the help
of an RF Transmitter creating an alarm during the case of
heart attack or any other health related problems. MSP430 is
coded using code composer studio.
So this product will be of great use to the medical industry
as well as to the common people and it can be called a Life
Saver.
IV Description :-
a. Microcontroller:-
It is a self-contained system with a processor, memory and
peripherals and can be used as an embedded system.
Microcontrollers has input/output devices ( sensors, LCD
displays, relays etc.), which is used for controlling the input
from the sensors and transmitting it to the receiver unit.
It has a dedicated input device and often has a small LED or
LCD display for output. A microcontroller also takes input
from the device it is controlling and controls the device by
sending signals to different components in the device.
b. RF Transmitter Receiver :-
RF transmitter and receiver is used to transmit data from the
microcontroller to the buzzer with a wifi module esp8266
through which data if transmitted from the transmitter to the
receiver. It is achieved through serial communication
between the transmitter and the receiver.
i. Serial communication:-
For communication between two devices on longer distances
is possible through serial communication. The factors which
influence it are the no of microcontroller used for exchange
of data and their speed and their distance between them. The
calibration of data being sent and received is done through
microcontroller MSP430 which is also called protocol.
Pulse oximitry sensor :-
A sensor device is placed on a thin part of the patient's body,
usually a fingertip or earlobe, or in the case of infants, across
a foot. The device passes two wavelengths of light through
the body part to a photo detector. It measures the changing
absorbance at each of the wavelengths, allowing it to
determine the absorbance’s due to the pulsing arterial
blood alone, excluding venous blood, skin, bone, muscle, fat,
and (in most cases) nail polish.[1]

HEALTH MONITORING SYSTEM WITH WIRELESS ALARM Kishoth Geethan,kishothgeet@gmail.com,+91-8428188410 Abstract :- The HEALTH MONITORING SYSTEM WITH WIRELESS ALARM is a device which will be of help to patients as well as the elderly people enabling their caretakers to easily take care of them. It transmits the data acquired from the sensors to the wireless alarm and display unit thereby enabling the caretaker to reach the patient faster in case of emergency this especially works if the caretaker thinks the patient is sleeping but is actually undergoing hypoglycemia or any other problem. The display unit immediately alerts the caretaker of the change in condition, preventing serious injury. This is achieved by detecting the heart rate and the temperature of the patient. Keywords: - healthMonitering,heartrate measurement, portable device. I.INTRODUCTION:- A heart rate monitor is a monitoring device that allows a subject to measure their pulses in real time or record their heart rate. Usually it is done by a monitoring box with a set of electrode leads attached to the chest. The heart rate of a healthy adult is around 72 beats per minute (bpm) an average human heart rate is(60-100)beats/minute. While measuring the rate when the pulse returns to normal is an indication of the fitness of the person. Lower than normal heart rates are usually an indication of a condition known as bradycardia, while higher is known as tachycardia. Heart rate is simply measured by placing the thumb over the subject’s arterial pulsation, and feeling, timing and counting the pulses usually in a 30 second period. This method although simple, is not accurate and can give errors when the rate is high. More sophisticated methods to measure the heart rate utilize electronic techniques. Electro-cardiogram (ECG) is one of frequently used method for measuring the heart rate. But it is an expensive device. Low-cost devices in the form of wrist watches are also available for the instantaneous measurement of the heart rate. Such devices can give accurate measurements but their cost is high. So this heart rate monitor with a temperature sensor is definitely a useful instrument in knowing the pulse and the temperature of the subject or the patient. Heart rate can be taken at any spot on the body at which an artery in close to the surface and a pulse can be felt. The most common places to measure heart rate using the palpation method is at the wrist (radial artery) and the neck (carotid artery). Many heart rate monitors require at least a little body perspiration between the chest strap and the skin for best conduction of the signal. II.PROCESS MODEL :- The Health Monitoring System with Wireless Alarm is a device which will help the elderly be properly taken care of. This will also be of use to the people who take care of them. People who use this device will able to be in peace knowing that they are perfectly safe when using this device.The Heart of the Health Monitoring System with Wireless Alarm is the MSP430 Micro Controller. The Heart Beat is recorded using Pulse Oximetry Sensor. The Pulse Oximetry Sensor will output the Heart Beat in the form of an Analog Signal. The Analog to Digital converter of the MSP430 Micro Controller is used to convert the Analog input into Digital form. This is done by taking the average of highest crest and lowest trough of the Analog waves for 200 readings we get the accurate reading. This reading is processed by the MSP430 Micro Controller to calculate the number of beats per minute. If the Heart Rate of the person is too low or too high the Micro Controller transmits the fact to the receiving unit by the means of a RF Transmitter. The Receiving unit is in fact another MPS430 Micro Controller connected to a RF Receiver and a Buzzer. During the event of Heart attack or any other related problems the transmitting unit signals the receiver to generate an alarm. This will in turn help get timely attention to the patient.
