The customer required a fast proof of concept solution for a pulse oximetry (SpO2) application.

• Bluetooth based hardware for capturing and transmitting SpO2 data
• iOS application for display and recording SpO2 & Heart Rate
• Embedded C Firmware
• Battery-powered, rechargeable
• Live updates to Firebase

Kelsec designed the solution using a Nordic SoC based module. The module contains the Nordic nRF51822 chipset (ARM Cortex M0) and is certified for FCC, CE, SIG.

• Pulse Oximetry hardware was designed quickly using a Nonin module.
• Kelsec created an iOS application for BLE communication with the board. The iOS application was written in Swift. The whole solution was ready in a matter of weeks.

• Oxygen Level (SpO2) and Heart rate using finger pulse oximetry
• Battery-powered, recharging using a micro USB connector
• Led for status
• iOS App running on iPhone, iPad. Display SpO2 level, Heart rate, and condition of the board.
