Pulsesensor Pulse Heartbeat Heart Rate Sensor bluetooth Compatible Module

Instructions PulseSensor is a photoelectric reflective analog sensor for pulse heart rate measurement Wear it on the finger earlobe etc through the wire connection the collected analog signal can be transmitted to the arduin0 and other single chip microcomputers for conversion to digital signals and then the heart rate value can be obtained by simple calculation by the arduin0 MCU and the pulse can be obtained The waveform is uploaded to the computer to display the waveform Feature Board diameter 16mmBoard thickness 1 6mm common PCB thickness LED peak wavelength 515nmSupply voltage 3 3v or 5vOutput signal type analog signalOutput signal size 0 3 3v 3 3v power supply or 0 5v 5v power supply Current size 4ma 5V Package includes 1 x Sensor with three DuPont lines 20cm the colors of the lines are random 4 x Black gluing1 x Ear clip 16mm 1 x Strap9 x Transparent film
