Abstract

An effort to avoid the transmission of the covid-19 virus and other infectious diseases during the pandemic continues to be developed. For patients infected with Covid-19, keeping their oxygen saturation and heart rate together at all times is very important. Generally monitoring of SpO2 and heart rate is done manually, so it takes continuous time by health workers. In this research, a device is designed that can unite SpO2 in blood and heart rate using the Blynk application. Measurement results can be monitored via the LCD and android. Android-based measurements can reduce the risk of health workers contracting the virus and information about patients can be monitored more quickly. This system is designed using NodeMCU Esp8266 as a microcontroller and a Max30100 sensor as a detector of oxygen levels and BPM. Data transmission comes from multiple tools in one application. The measurement results show that the data can be monitored with the value listed on the android the same as the value on the LCD.
