Overview
The Heart Rate 9 Click Board™ features the PIC16F1779 8-bit MCU and SFH 7060 heart rate and pulse oximetry monitoring sensor. This Click Board™ has an algorithm for processing data from the sensor and it can send data for 3 different diodes (Green, Infrared and Red) who give out a diagram of the heartbeat and its frequency per minute. The data has shown that the most notable signal comes from the green diode because it has the best reflection through the surface of the skin due to its shortest wavelength among three light sources. Implementing a light barrier to block optical crosstalk and improved geometry for optimized signal quality.
Most reflective heart rate monitors still have significant noise in their designs despite the use of complex and expensive analogue circuits such as Analog Front End (AFE) chips. A more cost-effective method for reducing noise and taking these measurements is necessary.
Das Heart Rate 9 Click Board™ verfügt über die PIC16F1779 8-Bit-MCU und den SFH 7060-Sensor zur Überwachung von Herzfrequenz und Pulsoximetrie. Dieses Click Board™ verfügt über einen Algorithmus zur Verarbeitung von Daten vom Sensor und kann Daten an 3 verschiedene Dioden (Grün, Infrarot und Rot) senden, die ein Diagramm des Herzschlags und seiner Frequenz pro Minute ausgeben. Die Daten haben gezeigt, dass das auffälligste Signal von der grünen Diode kommt, da sie aufgrund ihrer kürzesten Wellenlänge unter den drei Lichtquellen die beste Reflexion durch die Hautoberfläche aufweist. Implementierung einer Lichtbarriere zum Blockieren von optischem Übersprechen und verbesserte Geometrie für optimierte Signalqualität.
Die meisten reflektiven Herzfrequenzmonitore weisen trotz der Verwendung komplexer und teurer analoger Schaltkreise wie Analog Front End (AFE)-Chips immer noch erhebliches Rauschen auf. Es ist eine kostengünstigere Methode zur Reduzierung des Rauschens und zur Durchführung dieser Messungen erforderlich.
