HKG-07C+ Infrared Digital Pulse Sensor

HKG-07C infrared digital pulse sensor uses correlation type infrared to detect the changes of volume within fingertip microvascular, which caused by the heart beating, then by signal amplification, conditioning, AD converter and USB curcuits, the real changes will be converted digital signal and transferred to computer.
The sensor’s output signal is very similar to the outputs of pressure pulse sensor, it can be used for pulse waveform analysis in traditional Chinese medicine or western medicine field.
