GY-MAX30102 Heart Rate Pulse Oximeter Sensor Price in Bangladesh

The GY-MAX30102 Heart Rate Pulse Oximeter Sensor is a compact optical sensor module based on the MAX30102 integrated heart-rate and pulse-oximetry sensor. It is designed for electronic projects that require optical measurement of pulse-related signals and blood oxygen saturation (SpO2).

The MAX30102 integrates red and infrared LEDs, a photodetector, optical components, ambient-light cancellation, and low-noise signal-processing circuitry into a single sensor solution. Communication with a microcontroller is provided through an I²C-compatible interface.

The GY-MAX30102 breakout module makes this sensor practical for development and prototyping with platforms such as Arduino, ESP32, Raspberry Pi, and other microcontrollers with suitable I²C support. Commercial breakout boards can differ in PCB dimensions, power-input arrangement, and onboard circuitry, so the exact board version should be checked before integration.

This module is particularly useful for educational projects involving biomedical electronics, physiological signal acquisition, wearable technology, IoT, and optical sensing.

What is MAX30102?

MAX30102 is an integrated optical sensor designed for heart-rate monitoring and pulse oximetry. It combines red and infrared LEDs with a photodetector and signal-processing electronics.

The sensor detects changes in reflected light associated with blood-volume changes in tissue. These optical variations are known as photoplethysmography, or PPG. Suitable algorithms can then process the acquired signal to estimate heart rate and, in appropriate designs, SpO2.

Key Features

Heart-Rate Sensing

The MAX30102 can acquire optical PPG signals associated with changes in blood flow and is designed for heart-rate monitoring applications.

Pulse Oximetry Capability

The sensor’s red and infrared optical channels support pulse-oximetry applications where suitable signal-processing algorithms are implemented.

Red and Infrared LEDs

The MAX30102 integrates red and infrared LEDs. Common breakout documentation identifies peak wavelengths of approximately 660 nm and 880 nm.

I²C Communication

The module communicates digitally through an I²C-compatible interface, making it convenient to connect with microcontrollers and development boards.

Low-Power Design

The MAX30102 was designed for low-power wearable and portable applications. The manufacturer’s documentation specifies low-power heart-rate operation and a typical shutdown current of 0.7 µA for the IC.

Therefore, always follow the markings and specifications of the particular GY-MAX30102 board being used.

Working Principle

The GY-MAX30102 uses an optical sensing technique called photoplethysmography (PPG).

The integrated red and infrared LEDs illuminate tissue placed over the optical sensor. Some of the emitted light is absorbed or reflected differently as blood volume changes. The photodetector measures the resulting changes in reflected light.

The MAX30102 converts these optical signals into digital data that can be retrieved by a connected microcontroller through the I²C interface. Software can then process the PPG waveform to extract useful information such as pulse rate and, with appropriate algorithms and signal quality, oxygen-saturation estimates.

The quality of the result depends on factors such as sensor positioning, movement, ambient conditions, signal processing, and the implementation of the measurement algorithm.

Limitations

The GY-MAX30102 is a development and sensing module, not a certified medical diagnostic device. Readings from a hobby or development setup should not be treated as a substitute for professional medical equipment or clinical measurements.

Motion, poor sensor contact, ambient light, skin/tissue characteristics, and software algorithms can affect the quality of the acquired PPG signal. The sensor itself provides optical data; useful heart-rate or SpO2 values require appropriate signal processing and algorithms.

Also, different GY-MAX30102 breakout boards can have different onboard regulators, pull-up arrangements, dimensions, and supply requirements. Check the specific board markings before connecting it to a controller.

Installation / Usage Tips

Use the module with a compatible microcontroller and I²C connection. Confirm the board’s supply-voltage requirements before powering it.

For reliable optical signal acquisition, keep the sensing surface properly positioned and minimize unnecessary movement during measurement experiments. Excessive movement can introduce artifacts into the PPG signal.

Use an appropriate MAX30102 library or software implementation for the selected microcontroller and configure the sensor according to the requirements of the project.

For educational and research projects, it is useful to observe the raw PPG waveform before attempting to calculate heart rate or SpO2. This helps users understand how optical physiological signals are acquired and processed.
