Heart Rate Sensor

₹150₹20025% OFF

Component Technical Specifications

A Heart Rate Sensor (such as the MAX30102 or Pulse Sensor) uses Photoplethysmography (PPG) to detect blood volume changes in the capillary tissue. By shining a green or infrared LED into the skin and measuring the reflected light with a photodiode, it tracks the rhythmic "pulse" of the heart.Technical SpecificationsOperating Voltage3.3V to 5V DC.Communication: I2C interface (for digital modules) or Analog output.Wavelengths: Dual-LED setup (Red and IR) for SpO2 and Heart Rate monitoring.Current Consumption: Ultra-low power modes ($<1$mA) for wearable integration.Integrated Circuitry: Onboard noise cancellation and ambient light rejection.Key Features for MakersOptical Isolation: Designed to filter out motion artifacts and ambient light interference.Data Processing: Provides raw PPG data that can be processed via algorithms to calculate BPM (Beats Per Minute) and Heart Rate Variability (HRV).Form Factor: Compact, lightweight design suitable for finger-clip, wrist-strap, or chest-belt prototypes.
