5PCS Microphone Sensor Module High Sensitivity Sound Detection Sound Sensor Control Switch Module(Blue) 3.3-5V for Arduino with Dupont Cable

Sound sensor module:
1. Detect the sound intensity of the surrounding environment,Note to be used: This sensor can only identify the presence or absence of sound (in line with the vibration principle), but cannot identify the size of the sound or the sound of a specific frequency
2. Adjustable sensitivity(adjusted by the blue digital potentiometer in the picture)
3. Working voltage 3.3V-5V
4. Output form: digital switch output (0 and 1 low and high levels)
5. There are fixed bolt holes for simple installation

Instructions to be used:
1 The sound module is most sensitive to the ambient sound intensity, and is usually used to detect the sound intensity of the surrounding environment.
2 When the ambient sound intensity does not reach the set threshold, the OUT outputs a high level, and when the ambient sound intensity exceeds the set threshold, the module OUT output low level
3. The digital output OUT of the small board will also be in an instant connected to the single-chip microcomputer, and the low and high levels are detected by the single-chip microcomputer, thereby detecting the sound of our surroundings;
4 small board digital output OUT can in an instant drive our relay module, which can form a voice switch

Package includes:
5 x Microphone Sensor Module(Blue)
1 x 15Pin Female to Male Dupont Cable
