HiLetgo 5pcs Sound Sensor Module Voice Detect Voice Control Switch

Sound Sensor Module Voice Detect Voice Keep an eye on Switch

Features:
1. It”s for use for detecting the sound intensity of ambient.
2. Adjustable sensitivity (adjusted by the blue digital potentiometers)
3. Operating voltage 3.3V-5V
4. Output form: Digital switching outputs ( 0 and 1 low and high Level)
5. Easy installation with bolt hole
6. Small PCB Size : 3.2cm * 1.7cm

NOTE: This sensor can identify the presence or absence of sound (in keeping with the vibration principle ), but can’t recognize the volume of the sound and the frequency of sound.

Description:
1. Sound module is sensitive to the environment, usually for use to detect the intensity of the ambient sound.
2. If the module can’t reach to the threshold set in the environment of sound, OUT output high level. When the ambient sound level exceeds the set threshold, the module OUT output low level;
3. The digital ouput OUT at the small plates may also be right away connected to the microcontroller, detecting the sound environment by way of the microcontroller detecting low and high level.
4. The digital ouput OUT at the small plates can right away drive relay module, which works as a voice-activated switch; Module wiring instructions:
1. VCC external connect to 3.3V-5V voltage ( may also be right away connected to 5v and 3.3v MCU MCU )
2. GND to be connected to GND
3. OUT: Switch output interfaces ( 0 and 1 )

Package Includes:
5 * Sound Sensor Module
