MIKROE-3822, Heart Rate 9 Click Board based on PIC16F1779 8-bit MCU and SFH 7060 Heart Rate and Pulse Oximetry Monitoring Sensor

说明

• MIKROE-3822, Heart Rate 9 Click board which features PIC16F1779 8-bit MCU and SFH 7060 heart rate and pulse oximetry monitoring sensor. This click has an algorithm for processing data from the sensor and it can send data for 3 different diodes (green, ir, 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 analog circuits such as Analog Front End (AFE) chips. A more cost-effective method for reducing noise and taking these measurements is necessary
