According to WHO, road accidents crashes are the 9th leading cause of death and are responsible for 2.2% of all deaths worldwide. Almost 1.25 million people are dying in road accidents every year, about 3,287 deaths in a day. Additionally, 20-50 million people are injured or disabled. Unless action is taken, by 2030, road traffic accidents will become the fifth leading cause of death. Majority of the accidents in highways are due to over speeding and rash driving. Some accidents are also due to human fatigue and health issues of automobile drivers.
IoT healthcare also known as the internet of health things is one of the application of IoT for health and medical purposes, data acquisition and research, as well as monitoring of health. IoT it has a number of applications such as remote monitoring, medical device integration, smart sensors, etc. The remote monitoring systems include blood pressure, heart-rate monitors to specialized devices such as Fitbit, hearing aids, etc. Hospitals have also implemented “smart beds” that are able to detect when a patient is trying to get up.
It can adjust the pressure and support without manual interaction. Additionally, the use of mobile devices for real-time monitoring, storage, and transmission of health-related data collected from sensors and biomedical devices is termed as m-health or mobile-health.
IoT systems have also been recognized as a potential solution to identify human fatigue and recognize other health-related issues of the drivers, and are also capable of detecting if the vehicle is over speeding or cases of rash driving, etc.
There has been a considerable amount of research in the monitoring of health using IOT systems. Wearable ECG monitors, smart helmets to monitor neural and brain activity, systems to detect drowsiness have been developed.

Electrocardiogram (ECG) provides the best way to monitor human health. An electrocardiogram is the electrical activity of the human heart. It consists of a P-wave, QRS- complex, T-wave, U-wave. Using the features of these waves, it is possible to calculate the heart rate or beats per minute, detect any heart diseases such as a myocardial infarction. The heart rate of a normal person is 60 to 100 beats per minute. Any heart rate less than 60 bpm, accounts to a condition known as bradycardia and if the heart rate is more than 100 bpm, the condition is known as tachycardia. Using the heart rate and some additional information, other states of the driver such as stress, anxiety, drowsiness, alcohol consumption, the adrenaline rush can be detected.
The proposed system intends to realize a continuous ECG monitoring system for automotive drivers using the AD8232 ECG sensor and ESP32 microcontroller. It continuously records the ECG signals of the driver, filters it, detects the R-peaks, to calculate the heart rate, and also detects any abnormalities in the ECG signal due to any heart-related diseases using a polynomial regression approach. Upon the detection of any abnormalities, it provides an emergency notification system.
The system will be mainly composed of a central unit that is responsible of receiving information, and detecting heart beat , data collecting and transferring to the central unit. It is implemented with as low cost as possible to render its replacement affordable in case of a sudden heart attack .Ecg sensors will in this case act as mentors to control the unit. This will guarantee a high reduction of risk on their lives.
Ultrasonic sensors unit will communicate with the central unit to send speed information as soon as collecting them. This will insure the receiving of all necessary data even in case of losing the unit. Information transferred is typically the location of each detected suspected object and images from that location.
Nowadays people are driving very fast, accidents are occurring frequently, we lose our valuable life by making small mistakes while driving . To develop a system that can prevent fatal motor vehicular accidents due to abnormal health condition of the driver, over-speeding and undetected obstacles. To measure ECG signals of the driver, store it in a cloud and use machine learning to analyze the driver’s heart rate patterns and detect stress and fatal health problems. To detect over speeding of the vehicle using Ultrasonic sensors.PROPOSED SYSTEM
The system continuously monitors the driver’s ECG signals using an ECG sensor which is then sent to the microcontroller. The recorded ECG signal is processed using MATLAB to determine whether the driver is fit or unfit for driving. Based on the decision, a notification will be sent to the driver if he is unfit for driving.

G. Wolgast et al. In , body area network (BAN) with two electrodes for measuring an electrocardiogram (ECG) signal and one electrode for reference and transmitting it to a smartphone via Bluetooth for data analysis were described. The user’s own smartphone was utilized for data processing and can be used to generate an alert if an abnormal heart condition is detected. The system had three use cases: monitoring of ECGs of an individual, continuously, myocardial infarction and other fatal heart-related malfunctions could be detected hours before. During a myocardial infarction, the ECG readings of an individual have a distinct ST elevation, which can be used to detect heart attacks.
An arm-band based ECG sensor, which is easy to wear has also been described by Rachim & Chung , in which capacitive coupled electrodes were implanted in an armband. Silver coated polyester ECG electrodes were used which were all placed in a single arm-band. This armband sensed ECG signals and sent them to a smartphone via Bluetooth. Peak detection was done using Pan and Tompkins algorithm.
