The OB1203 is a fully integrated optical sensing module for Pulse Oximetry (PPG - photoplethysmography), multi-channel Color Sensing (CS), Ambient Light Sensing (LS) and Proximity Sensing (PS).
With the appropriate algorithm, it can determine human heart rate, blood oxygen saturation (SpO2), respiration rate and heart rate variability (a measure of stress). The OB1203 integrates all light sources, drivers, and the sensor elements, in a single optically optimized package.
A major application of the device is consumer and mobile devices, enabling biosensing features and display control in a single device. The OB1203 can determine proximity of nearby objects in order to support the deactivation of touch screen displays or the detection of a finger for pulse oximetry measurements, for example. The sensor combines optical sensing features (CS, LS, PS) and bio-sensing functionality (PPG) without the need for a transparent optical opening. The unique implementation of OB1203 enables SpO2 measurements behind IR transmissive ink, making the device virtually invisible, and allowing for aesthetic industrial designs.

A brief introduction to Renesas' biosensor module for heart rate, SpO2 and respiration using the highly integrated OB1203 for reflective photoplethysmography, light and color sensing. With the provided algorithm, the solution can determine heart rate, oxygen saturation (SpO2) and respiration rate. The sensor transmits its data via an I2C interface to an MCU for data analysis and result display. The evaluation kit also incorporates an RL78/G13 16-bit microcontroller, an ISL9111 high-efficiency synchronous boost converter for battery operation and an OLED display.
