Pulse Oximeter Heart Rate Sensor Module MAX30100


The MAX30100 is a sensor module that can measure both heart rate and blood oxygen saturation levels (SpO2). It utilizes a combination of LEDs and photodetectors to measure changes in light absorption caused by blood flow through the tissues.


Specifications:

  • Operating Voltage: 1.8V to 5.5V
  • Input Current:  20mA during operation
  • Communication Interface: I2C
  • Temperature Range: -40°C to +85°C
  • Temperature Accuracy:  ±1°C.
  • Heart Rate Range: 30 BPM to 200 BPM
  • SpO2 Range: 70% to 100%
  • ADC Resolution: 14 bits.
  • LED Drive Current: Up to 50mA
  • IR LED Peak Wavelength: 870-900 nm
  • Red LED Peak Wavelength: 650-670 nm
  • Power Consumption: Low

Additional features include:

  • Ultra Low Power Operation: It consumes 600μA during measurement mode and only 0.7μA in standby mode, making it suitable for wearable devices like smartwatches.
  • High Sample Rate Capability: The sensor can handle a high sample rate and provides fast data output.
  • Integrated Ambient Light Cancellation: It minimizes interference from ambient light.
  • On-Chip Temperature Sensor: The module includes an on-chip temperature sensor for accurate temperature readings.


Frequently Asked Questions About Pulse Oximeter Heart Rate Sensor Module MAX30100

Q1: How does the MAX30100 work?

The MAX30100 works by emitting a light into the tissue and measuring the amount of light absorbed by the tissue. The amount of light absorbed depends on the amount of blood flowing through the tissue, which varies with the heartbeat. The sensor then uses this information to calculate the heart rate and SpO2.

Q2: What are the applications of the MAX30100?

The MAX30100 is commonly used in wearable fitness trackers, medical devices, and other applications where monitoring heart rate and SpO2 levels is important.

Q3: What is SpO2?

SpO2 stands for peripheral capillary oxygen saturation. It is a measure of the amount of oxygen that is bound to hemoglobin in the blood and is expressed as a percentage.

Q4: How accurate is the MAX30100?

The accuracy of the MAX30100 depends on a variety of factors, including how the device is calibrated, the quality of the LEDs and photo detectors, and the placement of the sensor on the body. However, with proper calibration and placement, the MAX30100 can provide accurate measurements.

Q5: How is the MAX30100 calibrated?

The MAX30100 can be calibrated using a process known as signal averaging. This involves taking multiple readings and averaging them to reduce noise and improve accuracy.

Q6: What are some potential limitations of the MAX30100?

The MAX30100 may not provide accurate measurements in certain situations, such as when the sensor is not placed properly on the body or when there is excessive motion or ambient light. It may also be affected by skin color and thickness, as well as other factors such as altitude and temperature.

Q7: How do I use the MAX30100?

The MAX30100 can be used by connecting it to a microcontroller or other device and running software to process the data. The sensor should be placed on a finger, earlobe, or other body part with good blood flow, and the readings should be monitored for accuracy.


Applications:

  • Wearable Devices
  • Fitness Assistant Devices
