“MAX30102 is a complete system solution that simplifies the design process of mobile and portable devices. MAX30102 uses a 1.8V power supply and a separate 5.0V power supply for the internal LED. The communication is carried out through a standard I2C compatible interface. It can be shut down by software without a backup power supply, so that the power rail is always charged.
The built-in heart rate and blood oxygen module of MAX30102 is an upgraded version of MAX30100, which can be used to measure the heart rate and blood oxygen of the wrist and is used in smart clothing fields such as sports watches.”


NOTE:When using, please try to stick the sensor on your finger to avoid the influence of pressure changes on the data output. This product is a non-professional medical device and should not be used as an auxiliary device for medical diagnosis and treatment.
