MAX30100 Heart Rate Click Oximeter Pulse Sensor Module


৳ 500.00

Heart Rate Click MAX30100  for Arduino

Description:
Heart Rate click carries Maxim’s MAX30100 integrated pulse oximetry and heart-rate sensor. It’s an optical sensor that derives its readings

from emitting two wavelengths of light from two LEDs – a red and an infrared one – then measuring the absorbance of pulsing blood through a

photodetector. This particular LED color combination is optimized for reading the data through the tip of one’s finger. The signal is

processed by a low-noise analog signal processing unit and communicated to the target MCU through the mikroBUS I2C interface. Developers of

end-user applications should note that the readings can be negatively impacted by excess motion and changes in temperature. Also, too much

pressure can constrict capillary blood flow and therefore diminish the reliability of the data. A programmable INT pin is also available. Uses

3.3V power supply.

Key features:
Optical sensor: IR and red LED combined with photodetector
Measures absorbance of pulsing blood
I2C interface plus INT pin
3.3V power supply

Key Benefits:
Motion artefact resillence
Ambient light cancellation
Ready-to-use examples save development time
Supported in all MikroElektronika compilers

Applications

Developing algorithms for pulse oximetry and heart rate readings through the tip of a finger.

Package Included : 1 X MAX30100 Heart Rate Click Oximeter Pulse Sensor Module

Serial.print(“Initializing pulse oximeter..”);

// Initialize the PulseOximeter instance
// Failures are generally due to an improper I2C wiring, missing power supply

}
pox.setIRLedCurrent(MAX30100_LED_CURR_7_6MA);

// Register a callback for the beat detection
pox.setOnBeatDetectedCallback(onBeatDetected);
}

void loop()
{
// Make sure to call update as fast as possible
pox.update();
if (millis() – tsLastReport > REPORTING_PERIOD_MS) {
Serial.print(“Heart rate:”);
Serial.print(pox.getHeartRate());
Serial.print(“bpm / SpO2:”);
Serial.print(pox.getSpO2());
Serial.println(“%”);

tsLastReport = millis();
