Description

technical field [0001] The invention belongs to the field of photoelectric sensors, in particular to a heart rate measurement device and method based on the combination of multi-wavelength light sources and accelerometers. Background technique [0002] Most photoelectric heart rate sensors currently on the market use a single light source, such as green light or infrared light, to measure the user's PPG (photoplethysmography) signal, and then combine it with a G-sensor (three-axis accelerometer) or a motion sensor, etc. , to estimate and calculate the dynamic or static heart rate of the user. The existing photoelectric heart rate sensor has the following problems: when calculating the heart rate, it mainly depends on the measurement signal provided by the monochromatic light source, and the accuracy does not meet the ideal expectation. Contents of the invention [0003] The purpose of the present invention is to propose a heart rate measurement device and method based on ...
