DFRobot Gravity: MAX30102 heart rate and blood oxygen sensor module integrates the Maxim MAX30102 chip and an MCU with heart rate and blood oxygen algorithm.

The MAX30102 uses PPG(PhotoPlethysmoGraphy) to measure data, which will be converted into heart rate and oximetry values when processed by the MCU, then output through I2C or UART, making the sensor easy to use and greatly reducing resource occupation of the main controller. Meanwhile, the corresponding upper computer is provided to allow you to conveniently read data by a PC.

Note:

• The pressure may change when the finger is directly pressed down the sensor, which will affect the data output. So please try to fix the sensor on your finger.
• Wear the sensor on your finger and there is no difference in the direction of wearing.
• This product is not a professional medical instrument and should not be used as an auxiliary accessory in diagnosis and treatment

The DFRobot heart rate sensor is a thumb-sized heart rate monitor designed for Arduino microcontroller

This heart rate monitor sensor is a pulse sensor that is developed based on PPG techniques. This is a simple and low-cost optical technique that can be used to detect blood volume changes in the microvascular bed of tissues. It is relatively easy to detect the pulsatile component of the cardiac cycle according to this theory. The sensor has two holes that you can use to attach to your belt. You can wrap it on your finger, wrist, earlobe, or other areas where it has contact with your skin.

A gravityInterface is adapted to allow plug & play to ease the barrier of usage.  The io sensor shield is the best option to connect this heart rate sensor with your Arduino or other microcontrollers. Besides, this sensor can also be compatible with raspberry pie, intel Edison, joule, and curie by means of 3.3V Input Voltage.

The MAX30102 is an integrated pulse oximeter and heart rate monitor biosensor module. It integrates a red LED and an infrared LED, photodetector, optical components, and low-noise electronic circuitry with ambient light suppression.

It features a 1.8V power supply and a separate 5.0V power supply for internal LEDs for heart rate and blood oxygen acquisition in wearable devices, worn on the fingers, earlobe, and wrist. The standard I2C-compatible communication interface can transmit the collected values to the KL25Z and other microcontrollers for heart rate and blood oxygen calculation

In addition, the chip can also shut down the module through software, the standby current is close to zero, and the power supply is always maintained. Because of its excellent performance, the chip is widely used in the Samsung Galaxy S series mobile phones.

Compared with the previous generation MAX30100, the chip integrates a glass cover to effectively eliminate external and internal light interference and has the best reliable performance.
