Excellent sensitivity

This module detected claps across the room easily. The PH2.0 connector made wiring very clean.

Reliable detection

Integrated into my smart home system. No false triggers after calibration.

5 FAQ

Q: Can I use this with a Raspberry Pi?

A: Yes, but you will need an external ADC since Pi GPIOs are digital only.

Q: Do I need a specific library to read the data?

A: No, you can read the analog pin directly using standard analogRead functions.

Q: What is the effective range for sound detection?

A: Range depends on sensitivity settings and ambient noise, typically 1 to 3 meters.

Q: Is the PH2.0 cable included in the box?

A: Yes, a standard 3-pin PH2.0 cable is included with every module.

Q: Does this module support 3.3V logic levels?

A: Yes, this sensor operates comfortably between 3.3V and 5V DC.
