Abstract

There is growing concern about dangers correlated with driving, for people with known cardiovascular diseases. However, the association between having a chronic cardiovascular disease and being involved in a motor vehicle crash remains controversial. This study aims to monitor people with known medical emergencies or other medical conditions while driving [1]. It also helps the co-passengers to be cautious while the person is driving with an abnormal health condition. Designed it to be convenient and also can be easily adaptable by the end user.

The proposed project focuses on a wearable sensor glove that equipped with a pulse rate sensor, Temperature sensor, conductive thread, and an embedded system consisting of amplifier unit, power supply, microcontroller, and Zigbee transmitter unit. . This project consists of three systems: Transmitter, Receiver, and Wireless healthcare monitoring unit.

The transmitter section includes sensors, amplifier, processing unit and Zigbee for transmission. Here the pulse sensor uses a technique called Photoplethysmography (PPG) and temperature sensor used here is LM35. The pulse sensor mounted on the index finger of the gloves acquires the raw data from the human body and then sends to the microcontroller using conductive thread. The conductive thread sewed into the gloves feed the signal into the microcontroller. Data is analyzed by microcontroller and then sent to the receiver.

The receiver end consists of a Microcontroller, interfaced with display, storage unit, alarm, GPS, and GSM. Data from transmitter side is acquired using ZigBee receiver and sent to the Microcontroller, which is programmed such a way that the pulse rate and temperature parameters stored and displayed in real-time. When pulse rate and temperature are below or above the threshold, an alarm system is implemented to alert the co-passengers.
