The Sound Sensor Module uses an electret microphone and an LM393 comparator to detect sound. It gives a digital output when sound crosses the level set by the potentiometer, and an analog output for sound intensity – ideal for clap switches and noise detection.
| Microphone | Electret condenser |
|---|---|
| Comparator | LM393 |
| Supply voltage | 3.3V – 5V |
| Output | Digital (DO) + Analog (AO) |
| Adjustment | Potentiometer for sensitivity |
What is the operating voltage?
3.3V – 5V.
Can it record audio or recognise voice?
No, it only detects sound level. For voice commands use a voice recognition module like VC-02.
Can I buy the Sound Sensor Module Arduino Compatible in Kanpur?
Yes – buy online with delivery across India, or pick it up from the iTechBuilders store, Damodar Nagar, Kanpur.
