module sensor pulse (heartbeat) for Arduino will allow your device to measure the pulse of the person.
Sensor provides attachment on the finger, ear, or clothing. To sew the clothes on the board have special openings.
The basis of the pulse sensor consists of two components: a power LED and a special meter brightness. Blood pulsations cause a change in brightness of the reflected skin, leading to pulsation of the output signal.
On the way out heartbeat sensor an analog signal, which gives maximum flexibility. Integrated electronics amplifies the desired signal and clears it from interference.
The sensor is connected to the control electronics through 3 wires.
Use the module pulse sensor for Arduino can not only for medical purposes. For example, you can collect an electronic tester for the game that will accurately assess the degree of fright player in his pulse. Or email velotrenera that will help pass the distance at a fixed pulse.
