HRS3300 Heart Rate Sensor
Description
HALS3300 is an optical digital heart rate sensor, 525nm green LED and driver in a single 8-pin package.
The sensor incorporates with a fast, two-wire I2C bus (up to 800kHz) to communicate with micro-controller or embedded system. Its excellent background light rejection allows the device to operate in environments from sunlight to dark rooms.
The heart rate sensing is realized by using an 525nm green light LED with current driver, a reflection light detector for the PPG signal from the human body, as well as heart rate algorithm.
