Abstract

A countdown timer is a device or function in software that is designed to count down time from a starting point until it reaches zero. Its function is simple, namely to provide a visual or auditory indication of the remaining time remaining before a certain event or time limit is reached. The countdown timer implemented in this health device aims to provide clear time warnings to users regarding certain times related to health monitoring. For example, when using inhalers for asthma patients, a countdown timer can provide a countdown warning before the next inhalation, helping patients to follow the medication schedule more regularly. In this Countdown Timer series, we use an Arduino Uno manager to display it on the I2C 2x16 Liquid Crystal Display (LCD) and various other components. By implementing logic methods for countdown timers and alarms when the time reaches zero, it can provide an effective and efficient solution for monitoring critical time in various health applications, such as the use of inhaler medication for asthma patients. Further implementations may include integration with an RTC module for better timing accuracy and the use of additional sensors for more complex functions.

Abstract

The Fetal Doppler Simulator for calibration is a device designed to ensure the accuracy and reliability of Fetal Doppler equipment in monitoring fetal heart rate. Traditionally, calibration of Fetal Doppler devices has relied on limited methods with relatively high costs. Therefore, an alternative calibration medium that is more economical, practical, and reliable is needed. This simulator functions by generating fetal heartbeat signals with various rhythm patterns, ranging from normal conditions to pathological variations such as tachycardia and bradycardia. The research method applied was Research and Development (R&D), which included needs analysis, design planning, feature integration, prototype construction, and performance testing. The test results showed that the Fetal Doppler Simulator was able to generate stable heartbeat simulations with measurement values that remained within acceptable tolerance limits (≤5%). Based on these findings, it can be concluded that the development of this Fetal Doppler Simulator is feasible and effective as a calibration medium. This research is expected to offer a practical alternative for healthcare facilities to perform Fetal Doppler calibration at a lower cost.
