Summary of DIGITAL RGB / AMBIENT LIGHT, PROXIMITY AND PHOTOPLETHYSMOGRAPHY SENSOR
IDT's OB1203 is the industry's smallest all-in-one biosensor module (4.2mm × 2mm × 1.2mm) for mobile and wearable devices. It integrates heart rate, blood oxygen (SpO2), ambient light, RGB color, proximity sensors, and a pulse oximeter into one package. Featuring an antiallergenic glass cover for direct skin contact and operation under IR-inked glass for concealed designs, it outputs data via I2C with clinical-grade algorithms.
Parts used in the OB1203 Module:
- Ambient light sensor
- RGB color sensor
- Proximity sensor
- Pulse oximeter biosensor
- Two LEDs
- LED drivers
- Photo detectors
- Signal conditioning chip
- Antiallergenic glass cover
Integrated Device Technology (IDT), a wholly owned subsidiary of Renesas Electronics Corporation introduced the OB1203, a fully integrated all-in-one biosensor module for mobile and wearable devices. The OB1203 is the smallest sensor of its kind.
In addition to non-invasive measurement of heart rate and blood oxygen levels, the OB1203 module integrates additional sensors needed in the latest generation mobile devices, including an ambient light sensor (ALS), an RGB color sensor, a proximity sensor, and a pulse oximeter biosensor. This module comes in a tiny, optically-enhanced package at only 4.2 mm × 2 mm × 1.2 mm, and includes two LEDs, drivers, the sensors and a signal conditioning chip that outputs all sensor data on an I2C bus.
A key feature of the OB1203 is its antiallergenic glass cover, which allows it to be used in applications requiring direct skin contact. An additional advantage of the OB1203 is the ability to operate when covered with IR-inked glass, allowing product designers to almost entirely conceal the OB1203 for a cleaner, more aesthetically pleasing product design.
The OB1203 comes with clinical-grade heart rate (HR) and Sp02 algorithms, an easily customized Android app, and only requires power and three data lines to operate.
