Great for Arduino projects
Works perfectly with my Uno. Sensitivity is adjustable which is nice for different environments.

Sensitive and responsive
Picks up claps and voice clearly. Digital output threshold is easy to set with the onboard pot.

Perfect for school project
Easy to wire up. Documentation could be better but plenty of online tutorials available.

Works as expected
Had to tweak the potentiometer a bit but once set, it's stable. Fast shipping too.

Good value
Does what it says. Not professional grade dB measurement but good for triggers and basic detection.
Q: How do I wire the 4-pin interface?
A: Typically VCC, GND, DO, and AO. Please refer to the pinout diagram in the description.
Q: Is there a specific library for this?
A: It is a hardware sensor, standard analogRead functions work without specific libraries.
Q: Is the output analog or digital?
A: It provides both Analog (AO) and Digital (DO) outputs depending on your wiring.
Q: Does this work with 3.3V logic?
A: Yes, it supports 3.3V to 5V input voltage ranges.
Q: Can this measure exact decibels?
A: It detects sound intensity but requires calibration for precise dB readings.
