Mikroelektronika MIKROE-3218 BH1792GLC Optical Biosensor for Heart Rate Monitoring I2C Click Board

Technical description of the product (MIKROE-3218):

MIKROE-3218 BH1792GLC. Heart rate measurement solution, I2C, 3.3V, 5V. 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. Green light is most commonly used to measure the dilatation of blood vessels; therefore, Heart Rate 8 click is equipped with two green LEDs, driven by the BH1792GLC, a monolithic integrated sensor for heart rate monitoring. An additional IR LED is used to detect a finger touch. Heart Rate 8 click is a perfect solution for the development of various wearable health-related devices, smartphones, tablets, and similar space-constrained applications. Type: Biomedical Applications: Heart Rate 8 click is an ideal solution for the development of various wearable health-related devices, smartphones, tablet PCs, etc. On-board modules: BH1792GLC, a monolithic integrated sensor with I2C interface for heart rate monitoring, from ROHM Semiconductor company. Key Features: A complete heart rate measurement solution with constant current LED drivers, built-in photodiodes with filtering for both green and IR light spectrum, high integration ratio allowing a low number of external components, FIFO buffer for storing up to 35 samples, and more. Interface: I2C Input Voltage: 3.3V, 5V Click board size: M (42.9 x 25.4 mm).
