概要

This evaluation kit includes:

This OB1203SD-BT2-EVK evaluation kit for heart rate, oxygen saturation (SpO2) and respiration rate uses Renesas’ highly integrated OB1203 biosensor for reflective photoplethysmography.

With the provided algorithm (algorithm source code is available on request), the kit can determine heart rate, SpO2 and respiration rate. Data can be monitored locally by connecting a USB cable between the EVK and a computer and using a terminal program. Data is also sent by a wireless Bluetooth Low Energy (LE) link and available for monitoring using the Renesas OB1203 Web App running on a Windows V10 or later PC.
