Frequently Asked Questions
Frequently Asked Questions
What does this sensor detect?
It detects sound and changes in surrounding sound levels.
Can it detect a clap?
Yes. It can be used for clap-detection projects when the sensitivity is adjusted appropriately.
Can I use it with Arduino Uno?
Yes.
Can I use it with ESP32?
Yes. Make sure the sensor's output voltage is suitable for the ESP32's GPIO/ADC input.
Can I adjust the sensitivity?
Yes. Common versions have an onboard potentiometer for adjusting the detection threshold.
Does it measure sound in decibels?
Not directly. This module is primarily intended for sound detection rather than calibrated dB measurement.
Can I use it for a security alarm?
Yes. It can be used as part of a project that triggers an alarm when a specified sound threshold is detected.
