An optoelectronic sensor (01), a control method for the optoelectronic sensor (01), and a pulse monitor including the optoelectronic sensor (01). The optoelectronic sensor (01) may include a light source (10), a first receiver (20), a second receiver (30), and a phantom material layer (40) that is facing a light-emitting side of the light source (10) and at least partially overlapping with the second receiver (30).
