A heart rate pulse sensor module is a device used to measure the heart rate of an individual. It typically consists of an infrared LED and a photodetector placed on the fingertip or earlobe. The LED emits light into the skin, and the photodetector measures the amount of light that is reflected back. As blood pulses through the capillaries, it absorbs more light, causing fluctuations in the amount of light detected by the photodetector. These fluctuations are then processed to calculate the heart rate. The output can be in the form of analog voltage, digital signal, or directly displayed on a screen, depending on the specific module. Heart rate pulse sensor modules are commonly used in wearable devices such as fitness trackers, smartwatches, and medical monitoring devices for tracking heart rate during physical activity or monitoring health conditions. They are also used in various DIY projects and educational purposes to demonstrate physiological measurements.
