Capsule Electret Condenser Microphones 9.5mm MIC

This detection module combines a phototransistor and an LED that, when placed on a finger or ear lobe, provides a reading.
By reading this signal you can interpret a change in the signal as a heartbeat.
Keep in mind that this is a sensitive module and you will experience the noise from home lights and other sources, since minimizing the lighting of the unit will help get the readings.
