Abstract: The present disclosure relates to a PPG signal collection method and apparatus. The method includes: collecting, by using a light sensor, a first PPG detection signal formed by a first light source, where the first light source is a green light source; collecting, by using the light sensor, a second PPG detection signal formed by a second light source, where the second light source is a red light source; further, determining, according to the first PPG detection signal, whether the first light source meets a preset collection indicator; if the first light source meets the collection indicator, determining, according to the second PPG detection signal, whether the second light source meets the collection indicator; and if the second light source meets the collection indicator, collecting, by using the light sensor, a PPG signal formed by the second light source.
