This tiny module is a breakout board for the Maxim MAX30102 which is a high-sensitivity pulse oximeter and heart-rate sensor for wearable health. The sensor relies on two integrated LEDs, a photosensitive element, and a very accurate and advanced low noise analog front end to provide clean and accurate readings. It is enough to place an index finger on top of the sensor to get both heart rate and blood oxygen saturation readings via the I2C interface. Features such as the Ambient Light Cancellation (ALC) and the discrete time filters ensure that no ambient light or 50/60Hz hum is interfering with the readings.
