Precautions

 

Features:

  • Use IR LED and an optical transistor to detect pulsation in fingers
  • Small and Compact module
  • Easy to use
  • M2 Mounting holes (centres 10mm apart)
  • Designed to be compatible with standard 2.54mm sockets

Description:

  • This KY-039 Finger Detection Heartbeat Measuring Sensor Module uses bright infrared (IR) LED and a phototransistor to detect the pulse of the finger, a red LED flashes with each pulse
  • The LED is the light side of the finger, and the phototransistor on the other side of the finger, phototransistor used to obtain the flux emitted, when the blood pressure pulse by the finger when the resistance of the phototransistor will be slightly changed.
  • We chose a very high resistance resistor R1, because most of the light through the finger is absorbed, it is desirable phototransistor sensitive enough. Resistance can be 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, so faint heartbeat will add considerable noise.
