Title:: Development of a Universal, Portable Bluetooth Low Energy (BLE) Data Logger for Biomedical Sensor Applications

Information:: Abstract: In this work, we present a portable, open-source data logger with fully enclosed hardware that supports modification and operation under demanding conditions such as 100% relative humidity and exposure to chemical disinfectants. Based on a Raspberry Pi Zero W (RPI), the system manages BLE communication with various sensors to extract, analyse and store biomedical data during runtime. Its architecture is extensible with medical-grade, consumer-grade and custom-made hardware for multisensory applications. A web interface enables configuration and data export, making the device suitable for biomedical research. As an example, a Polar H10 sports chest strap is used for ECG- and acceleration (ACC) measurements.
