Mikroelektronika MIKROE-2998 Heart Rate 7 Click Optical Biosensor Module

Technical description of the product (MIKROE-2998):

Heart Rate 7 click is an optical biosensor Click board™ designed for heart-rate monitoring (HRM). This Click board™ utilizes a highly sensitive analog front-end IC with a wide dynamic range, ensuring precise and dependable readings. It integrates an optical front end, comprising a sensitive photo-diode (PD) and two high-brightness green LEDs. The photo-diode exhibits maximum sensitivity to the visible light spectrum, providing a high current output for highly accurate HRM measurements. Type: Biomedical. Applications: Ideal for developing applications focused on heart rate monitoring, calorie expenditure, and similar health-related functionalities. On-board modules: AFE4404 (integrated AFE for optical heart-rate monitoring and bio-sensing from Texas Instruments); VEMD8080 (high-speed photosensor from Vishay); VLMTG1400 (high-brightness true-green LED from Vishay). Key Features: High dynamic sensitivity; 3 integrated LED drivers with independently programmable currents; ambient light and DC offset cancellation; internal/external clock source; top-of-the-class LED and PD optical front-end from Vishay. Key Benefits: Simple and accurate HRM measurement, achieved by merely placing a finger on the sensor. Interface: I2C, PWM. Input Voltage: 5V, 3.3V. Click board size: M (42.9 x 25.4 mm).
