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

SPECIFICATION

Package Includes:

1 x DFRobot Gravity: MAX30102 Heart Rate and Oximeter Sensor

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.

This sensor module integrates gesture recognition and touch detects functions in one piece, and provides an adjustable detection range within 0~30cm. When connected to your microcontroller, it can detect a 5-way touch signal and 7 kinds of gestures: move left, move right, move forward, move backward, pull up, pull down, pull, and remove. Besides, the sensor is also equipped with the function of auto-sleep and waking up. The module comes with the gesture recognition algorithm and provides simple and reliable data output. Use the sensor to directly communicate with upper computer or micro-controllers like Arduino and Raspberry Pi via serial port

The outer shield for the sensor retains the advantages of the Gravity series as well as makes the sensor more durable. This sensor can be used to make smart lamps, DIY intelligent cars, or used in interactive projects requiring gesture recognition.
