Description
Microphone Sound Sensor Module by DaguRobot
Output Type: Digital output, analog output
Interface mode: pH2.0~4P
Working Voltage: 3.3 V ~ 5 V
Used to receive sound waves and display vibration images
The DaguRobot Microphone Sound Sensor Module is used to receive sound waves and display vibration images, but it can not measure the intensity of noise. The sound wave makes the electret film in the microphone vibrate, resulting in the change of capacitance, thus generating the corresponding change of micro voltage, which is received by the data collector through digital or analog conversion, and transmitted to the control board.
The analog output microphone received a sound signal in real-time. Do when the sound intensity reaches a certain threshold, the low-level signal is output (which can be adjusted by R2 on the module). Because the time of outputting the low-level signal is very short, in order to capture useful information, information filtering or interruption is used to present, here information filtering is used.
