Analog MEMS Microphone

Analog MEMS Microphone

$8.00

The analog MEMS microphone (SPM0404HD5-PB) is ideal for picking up audio signals that are loud or close to the port of the microphone (these are common in smartphones). The MEMS mic has a nearly flat frequency response from 100Hz - 10kHz, within 4dB, making it ideal for recording human voices at close range. The MEMS mic can also be used to record ambient sounds and an array of these SPM0404HD5-PB microphones can be used for sound localization by wiring to multiple analog pins on an Arduino board.

Included with the Analog MEMS Microphone:

  • 1x Analog MEMS Microphone Module (SPM0404HD5-PB)

  • 1x 3-Pin Header

Features of the Analog MEMS Microphone:

  • 3.0V-7.0V Supply Range

  • -42dBV/Pa Sensitivity

  • 59dBA Signal-to-Noise Ratio (SNR) @ 1kHz

  • 16mm x 15mm x 3.1mm Module Dimensions

  • 4.72mm x 3.76mm MEMS Microphone Dimensions

  • 100Hz - 10kHz Frequency Range (within 4dB)

  • 3mA - 10mA Average Consumption

  • SPM0404HD5-PB MEMS Microphone Datasheet

  • Video Demonstration with Arduino

NOTE: This sensor is quite sensitive to noisy power supplies. Thus, it is recommended that when setting up a recording system — the user must ensure a quiet power supply is being used. Otherwise, there will be pops and crackles in the signal.
