Microprocessor Coding For Biometric Device

The objective of this research project was to create a wearable device that monitors bodily functions for the user to view on their smartphone. Sensor data is processed using the Arduino Nano 33 BLE microcontroller. The sensors used in this project include proximity, temperature, humidity, heart rate, pressure, and skin impedance. This project takes advantage of the Arduinos Bluetooth low energy (BLE) capabilities so that all the data can be transmitted to a smartphone. This presentation examines the challenges of programming these devices, such as sensor timing, challenges related to heart rate processing, and Bluetooth transmission. Even though the device worked correctly, using two Arduinos to process the data doubles the power consumption. The signal processing may be improved upon by using a single device which contains two processing cores
