Finger Clip Heart Rate Sensor

This fin­ger Clip Heart rate sen­sor uses an IR emit­ter and a receiv­er to detect pulse of fin­ger. it can be used to mon­i­tor heart rate of patient and ath­lete. Note that the sig­nal of this sen­sor is so small(about 100mv) that an ampli­fi­er maybe need­ed. The result can be sam­pled by Arduino and saved for analy­sis. The entire sys­tem has a high sen­si­tiv­i­ty, low pow­er con­sump­tion and is very portable.SpecificationPow­er Supply:5V
