Enhanced Device for Monitoring the Vital Functions of Athletes Using Arduino UNO with Alcohol and Drug Sensor and Wi-Fi Module

Abstract: This paper presents the development of a smart monitoring system designed to measure and analyze key physi- ological parameters of athletes using an Arduino UNO micro- controller. The system integrates multiple sensors to monitorvital signs and enhance athlete safety during training and competitions.ThecorecomponentsincludeaDHT11sensor for environmental monitoring (temperature and humidity), a BMP180 sensor for measuring pressure and a GY-MAX30100 module for heart rate. Notably, the system estimates blood pressure (BP) by calculating Pulse Transit Time (PTT), which measures the time delay between the pulse detected by the MAX30100 and pressure changes captured by the BMP180.PTT is inversely correlated with BP and provides accurate estimations.AdditionalsafetyfeaturesincludeanMQ-3sensorto detect alcohol levels and an MQ-135 sensor to identify benzene- based compounds commonly associated with drug use. The outputs are displayed on a 16x2 LCD screen, and a buzzer triggersauditoryalertsforabnormalconditions.AWi-Fimodule facilitates real-time data transmission to a remote monitoring system, enabling coaches and medical professionals to assess the athlete’s condition instantly. By continuously tracking essential health parameters, the system enhances athlete safety, promotes optimal performance, and ensures early detection of potential health risks.
