A PPG sensor is used to measure the pulse rate, which detects the changes in blood flow to the tissue. The sensor consists of a single green or red/infrared double LED light source and a light sensor (photodiode). The light emitted from the light source is either penetrated or reflected...
Now, connect the Vcc and ground pin of the sensor to Arduino and the analog pin of the sensor to A0 of Arduino. All the apparatus is now set and ready to be used. We will put the sensor directly on the vein, either on the finger or the ear to measure the heart rate. Step 4: ...
(B)Taking your pulse during physical activity allows you to measure how hard you are exercising.You should exercise to stay within your target heart range.Use your index finger(食指) and middle finger. Don't use your thumb(拇指)-it has a pulse of its own.. Place these two fingers on ...

up the most common spot to reach for to measure your pulse is the artery on the thumb-side of the wrist. Touch this area lightly until you feel your pulse/heart beat. Count the amount of heart beats for 15 seconds and multiply by four – this will give you your daily pulse rate. ...
Stay on top of your blood pressure with the Blood Pressure app. Using the internal Photoplethysmogram (PPG) sensor in your Galaxy Watch, the Blood Pressure app measures your systolic and diastolic pressure, as well as your pulse rate. The Blood Pressure app is available ...
(d) Using the FPGA to measure the duty cycle The FPGA has an accurate 40 MHz clock-driven counter resource. The pulse width and period of the PWM wave can be calculated by recording the counter value of the signal along the changing moment, so as to ...
