Heartbeat detector, Heartbeat sensor module

Description

  • 100% brand new and high quality.
  • Pulse monitor works as follows: The LED is the light side of the finger, and photo transistor on the other side of the finger
  • The device also can  used as a signal generator for electric speed controller (ESC), then you can test your motor system without using a transmitter and receiver.
  • Photo transistor used to obtain the flux emitted, when the blood pressure pulse by the finger when the resistance of the phototransistor will  slight changed
  • Choosing a very high resistance resistor R1, because most of the light through the finger is absorbedResistance can  selected by experiment to get the best results. The most important is to keep the shield stray light into the phototransistor.
  • For home lighting that is particularly important because the lights at home mostly based 50HZ or 60HZ fluctuate,
