Overview
Wir präsentieren das Heart Rate 11 Click Board™
Wenn Sie nach einer kompakten Zusatzplatine suchen, die sich perfekt für Anwendungen zur Herzfrequenzüberwachung eignet, dann ist das Heart Rate 11 Click Board™ genau das Richtige für Sie. Mit dem OB1203 von Renesas, einem Mehrkanal-Lichtsensor (LS/CS), einem Näherungssensor (PS) und einem Photoplethysmographiesensor (PPG) ist diese Platine die ideale Lösung für Ihre Überwachungsanforderungen.
Erweiterte Sensorfunktionen
Der OB1203 auf dem Heart Rate 11 Click Board™ kann als Umgebungslichtsensor fungieren, ähnlich wie das menschliche Auge. Er kann auch als RGB-Farbsensor konfiguriert werden, was noch präzisere Messungen ermöglicht. Der OB1203 kommuniziert vollständig über eine standardmäßige I2C-kompatible Schnittstelle und verfügt über einen vollständig integrierten Biosensor für die reflektierende Photoplethysmographie. Mit dem entsprechenden Algorithmus kann dieses Click Board™ die menschliche Herzfrequenz (HR), Sauerstoffsättigung (SpO2), Atemfrequenz und Herzfrequenzvariabilität (ein Maß für Stress) bestimmen.
Einfach zu verwenden und zu entwickeln
Das Heart Rate 11 Click Board™ wird von einer mikroSDK-kompatiblen Bibliothek unterstützt, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Das bedeutet, dass Sie schnell und einfach loslegen können, ohne sich um komplizierte Softwareentwicklung kümmern zu müssen. Da das Click Board™ ein vollständig getestetes Produkt ist, kann es auf jedem System verwendet werden, das mit der mikroBUS™-Buchse ausgestattet ist.

How Does The Heart Rate 11 Click Board™ Work?
The Heart Rate 11 Click Board™ as its foundation uses the OB1203, a fully integrated all-in-one biosensor module that measures heart rate and blood oxygen levels from Renesas. The OB1203 combines all light sources, drivers, and sensor elements, in a single optically optimized package and can be used with just one side of a user's finger because it uses the space-conserving reflective PPG method. The appropriate algorithm can determine human heart rate, respiration rate, and heart rate variability (a measure of stress) or blood oxygen saturation (SpO2) behind IR transmissive but visibly dark ink, allowing implementation in aesthetic industrial designs.
The biosensor module contains different photodiodes for light (R, G, B, and Clear channels), proximity measurements, photoplethysmography, and temperature compensation of the light sensor. Those diodes are arranged in a matrix array, while the single diode for PS/PPG measurement is located below the matrix. The current photodiode is then converted to digital values by an analog-to-digital converter (ADC) and then forwarded via a serial interface for further processing.
The OB1203 communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 400kHz, fully adjustable through software registers. Also, it uses an interrupt pin, the INT pin of the mikroBUS™ socket, indicating when a specific interrupt event occurs, such as light, proximity, or photoplethysmography threshold crossed.
The Heart Rate 11 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
