![]() This change in volume of capillary tissues affects the LED light of heart rate pulse sensor, which transmits light after each heartbeat. As a result, the volume of capillary tissues is increased but this volume is decreased after each heartbeat. Similarly, when the human blood is circulated in human body then this blood is squeezed in capillary tissues. If we talk about heartbeat rate, then heartbeat rate is the ratio of time between two consecutive heartbeats. The working principle of this heartbeat rate sensor is very simple. The table below shows some key specifications of the SEN-11574 sensor. It is easily available in the market or online shops. This is basically plugged and play heartbeat sensor and can be used by athletes, game developers, and students in their hardware projects. For measuring this periodic intimation signal, many sensors have been used currently in the market but here we shall only talk about SEN-11574 pulse sensor amped. ![]() If we talk about heartbeat, then heart beat is a periodic signal that is produced by any software or hardware system for giving intimation to normal of working of any system. Normally it is a very difficult task to measure the exact heartbeat rate, but this has become so much easy with the help of this pulse sensor amped. The SEN-11574 pulse sensor is mainly used for sensing heartbeat rate.
