Description
The sound module is the most sensitive to the environment sound intensity, commonly used to detect the intensity of the sound of the surroundings.
Note: the sound sensor can identify the presence of sound
(according to the principle of vibration) or a particular frequency of sound does not recognize the volume of the sound.
Features:
- Signal output indication.
- The output is digital.
- Single-channel signal output.
- Output low level and the signal light when there is sound.
- Sensitivity adjustable digital potentiometer to adjust (blue)
- Working voltage 3.3-5V
- Output form: digital switch output (0 and 1)
- Dimensions: Length 32mm X Width 17mm X Height 15mm
- Main chip: LM393, electret microphone
Module wiring:
VCC voltage is 3.3 V to 5 V converter (which can be directly connected to 3.3 V or 5 V single-chip microcontroller)
GND external to GND
OUT of small plate switch output interface (0 and 1)
Package included:
1 x Sound Sensor Module
