Heart Rate 8 click is an optical biosensor Click board™, designed for heart-rate monitoring (HRM). This Click board™ employs a specialized sensor that incorporates three LED drivers and two photo-sensing elements, sensitive to green and IR light. The green light is most commonly used to measure the dilatation of the blood vessels, therefore, Heart rate 8 click is equipped with two green LEDs, which are driven by the BH1792GLC, a monolithic integrated sensor for heart rate monitoring, and the additional IR LED, used to detect a finger touch. Heart rate 8 click is a perfect solution for the development of various wearable health-related devices, smart phones, tablets, and similar space-constrained applications.It comes in the package which also includes the mikroSDK™ software and a library with all the functions.
