BOSON: Heart Rate Monitor Sensor i20

The heart rate monitor sensor can be used to detect heart rate changes despite a thumb size. It uses optical technology to detect the amount of blood oxygen in the subcutaneous capillaries to detect the corresponding human heart rate, so that the module can easily and conveniently measure the heart rate. The heart rate detector can be widely used in wearable devices, fitness equipment, and other scenarios. It works well with maincontrollers like Arduino, micro:bit, etc., and also supports graphical programming platforms such as MakeCode, and Mind+ as well as non-programming function.
