Great starter sensor
As someone new to electronics, this was easy to connect. The 3-pin and 4-pin compatibility meant I didn't need extra adapters. It lit up the LED immediately when I clapped.

Works but needs calibration
The sensor functions as described, but it took some time to calibrate the sensitivity to ignore background fan noise. Once calibrated, it triggers accurately. Just be patient during setup.

Perfect for my noise monitoring project
This sensor works flawlessly with my Arduino Uno. The analog output is stable, and the digital threshold is easy to adjust using the onboard potentiometer. Great value for the price.

Compact and reliable
I used this for a clap-switch robot. The response time is incredibly fast, and the small form factor made it easy to mount on the chassis. Highly recommended for hobbyists.

Good sensitivity, clear instructions needed
The module detects sound very well, even quiet whispers. However, beginners might need to look up a tutorial to understand the difference between the DO and AO pins. Once set up, it works great.

Solid performance for home automation
Integrated this into my smart home system to detect glass breaking alerts. It's sensitive enough for the task. I wish the cable was slightly longer, but that's a minor issue.
Q: Can this module measure exact decibel numbers directly?
A: This module provides an analog voltage proportional to sound intensity. To get specific decibel values, you must map the analog reading to a dB scale using calibration code on your microcontroller.
Q: Is the digital output pin active high or active low?
A: The digital output (DO) is typically active high by default, meaning it goes HIGH when sound exceeds the threshold. This can often be inverted via code depending on your logic requirements.
Q: Can I use this outdoors?
A: The PCB itself is not weatherproof. For outdoor use, you must house the module in a waterproof enclosure while ensuring the microphone hole remains unobstructed.
Q: Does this work with 3.3V logic boards like ESP8266?
A: Yes, the module operates comfortably within the 3.3V to 5V range, making it fully compatible with ESP8266, ESP32, and standard 5V Arduino boards.
Q: What is the maximum distance it can detect a clap?
A: Detection distance depends on ambient noise and clap volume. In a quiet room, it can reliably detect a sharp clap from approximately 3 to 5 meters away.
