The product number of Sensor-MIC is: MSDT11

Sensor-MIC is sound detection sensor module.

Electret microphone is composed of sound electric conversion and impedance conversion. The key component of sound electric conversion is electret diaphragm, which is a slice of thin plastic film of which one side is steamed with a layer of metal film, and after the electret by high voltage field, the two sides respectively has opposite charges, the steamed gold face of the diaphragm is outward, and is connected with the metal case. In the electret microphone, there is a field effect tube to do pre amplifier, so a certain blas voltage is needed when the electret microphone is working normally, which is generally not greater than 10v.

Microphone Sensor
General Pin Out Sensor / Trinket's Pin Out
PIN1 (GND) GND
PIN2 (VCC) VCC
PIN3 (SIGNAL-A) Analog Input
PIN4 (SIGNAL-B) Not Connected
  • General Pin Out is the standard pin out of a Sensor / Trinket connector.
  • Sensor / Trinket's Pin Out is this specific Sensor / Trinket's wiring in relation to the General Pin Out.
  • SIGNAL-A / SIGNAL-B are signals that could be digital input, digital output, analog input or analog output. Or special signals such as serial communication (SoftwareSerial, IIC (I2C), etc) or other special signals.
  • Not Connected refers to the Pin not being used for this particular Sensor / Trinket.
  • Read more about the hub module.
