DESIGN AND APPLICATION OF PORTABLE HEART RATE AND WEIGHT MEASURING TOOL FOR PREMATURE BABY WITH MICROCONTROLLER BASE

Abstract

Nowadays, premature baby can be caring by the parent using rental incubator. But it needs
high cost and lack of direct medical supervision of nurses and doctors. Many researches about incubator have
been conducted such as monitoring and controlling to temperature and humidity. Besides those parameters,
heart rate and baby weight is needed to be considered. The objective of this study is a portable monitoring
system for temperature, weight and baby heart rate in incubators. This system monitored using LCD on the
incubator and using WEB on smartphone/PC to check the system from another place. The data system is
displayed in real time and saved in database server. The client web server is used to microcontroller
communication on Ethernet network for monitoring system, so it can be accessed via internet through web
interface. Then, the application of Ethernet Shield as Web interface protocol for data transmission between
monitoring system devices using http interface protocol for long distance communication. The results of
monitoring data are expected to be a medical record of baby health conditions in incubators using this
portable system. In this paper is discuss two input parameters, the baby weight measurement section using
loadcell sensor and baby heart rate measurement using pulse sensor. The sensors are controlled by
microcontroller, LCD to display the output of sensor parameters and buzzer as indicator alert. The test results
of both parameters show the device has operated well and can be applied to measure the heart rate and
measure the baby's weight on incubator.
