OB1203SD-BT2-EVK
Evaluation kit for Heart Rate, SpO2, and Respiration Rate
The OB1203SD-BT2-EVK evaluation kit for Heart
Rate, SpO2, and Respiration Rate uses Renesas'
highly integrated OB1203 biosensor for reflective
photoplethysmography.
With the provided algorithm, the kit can determine
Heart Rate, Oxygen Saturation (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 (BLE) link and available
for monitoring using the Renesas OB1203 Web App
running on a Windows™ v10 or later PC.
The design incorporates a Dialog DA14531MOD
SmartBond TINY™ Module for MCU+BLE capability
and a Renesas ISL9111 DC-DC boost converter.
Functions
■
Collects data from Renesas OB1203 sensor
module through I2C communication
■
Calculates the oxygen saturation, pulse, and
respiration rate using the provided algorithm
■
Reports oxygen saturation, pulse, and respiration
rate raw data and tabular summary values plus
battery level
■
Boosts battery voltage to system's voltage needs
Target Devices
■
MCU+BLE: Dialog DA14531MOD module
■
Sensor: OB1203 module
■
Boost: ISL9111 (ISL9111EH33Z)
When applying the provided algorithm to another
microcontroller, modify the program to the
specifications for the target microcontroller and
conduct an extensive evaluation of the modified
program. Changes in analog or power supply
components also must be fully evaluated.
