HKG -07A infrared pulse sensor use the infrared ray In the examination fingertip blood vessel the volume occurs change because of the heart beats.

Output synchronization the pulse signal which beats to the pulse ,enlarges 、 recuperates 、 the reshaping after the signal ， that can calculates the Pulse profile. Mainly uses on the clinical arteries rate survey, the monitor and so on.
