Overview

Description

The evaluation kit for heart rate, oxygen saturation (SpO2) and respiration rate uses Renesas’ highly integrated OB1203 biosensor for reflective photoplethysmography. With the provided algorithm, the kit can determine heart rate, SpO2 and respiration rate. The sensor transmits its data via an I2C interface to an MCU for data analysis and results display. The design incorporates an RL78/G13 16-bit microcontroller as the MCU, an ISL9111 voltage boost converter for battery operation and an OLED display.
