A novel approach for IoT based wearable health monitoring and messaging system

A smart, non-invasive wearable physiological parameters monitoring device has been developed and reported in this paper. The proposed system monitors body temperature, heart rate and is able to detect fall of a human subject. The devise houses several sensors to measure vital parameters of an individual. A user interface platform on an android-based mobile phone has also been developed to keep track of the human health through a wireless network from anywhere in the world. The device detects whether a person is medically distressed and automatically sends a text message to his/her caregiver or to the concerned doctor for proper attention along with his/her location. The implemented heart rate sensor avoids the use of discrete components as compared to traditional photo-plethysmography (PPG) circuit. The proposed digital filter directly filtered the signal of TCRT1000 which is processed inside the programming board to increase the accuracy of heart rate measurement and to minimize the power consumption. The device is battery powered and can be easily adapted to monitor athletes, infants and old aged people. Finally, the overall heath credential is updated online on the developed Fusion table, which can be accessed via email.
