Reliable and durable
I have been using this module for six months in a home automation setup to detect glass breaking sounds. It has never failed me. The build quality is solid, and the connector is secure.

Great value for learning
Bought this for a school robotics project. It was very easy to connect using the Gravity interface. The only reason I didn't give 5 stars is that the included documentation could be slightly more detailed for absolute beginners.

Good sensitivity range
The sensor picks up a wide range of sound frequencies. It's great for general detection. Just keep in mind it measures amplitude, not specific frequencies, which is expected for this price point.

Easy to integrate
As someone new to electronics, I appreciated how plug-and-play this is. No soldering required if you have the compatible cables. The sample code provided on the wiki got me up and running in minutes.

Perfect for noise monitoring projects
This sensor works flawlessly with my Arduino Uno. The analog output is stable and easy to read. I used it to build a simple noise level meter for my workshop, and the sensitivity is adjustable enough for various environments.

Excellent addition to the Gravity series
DFRobot continues to impress with their Gravity line. This sound sensor matches the quality of their other modules. The form factor is compact, making it easy to fit into small enclosures.
Q: Is a data cable included in the package?
A: Yes, the package includes one Gravity 3-pin analog data cable compatible with standard Arduino boards.
Q: What is the maximum voltage this module can handle?
A: The module operates safely between 3.3V and 5V DC. Applying voltage higher than 5V may damage the sensor.
Q: Can this detect human voice specifically?
A: The sensor detects sound pressure levels across a broad frequency range. It can detect human voice but cannot distinguish it from other noises of similar volume without additional software processing.
Q: Does this sensor output digital signals or only analog?
A: This specific model outputs an analog signal proportional to the sound intensity. If you need a digital trigger output, please check our Digital Sound Sensor models.
Q: Is there a library available for Python on Raspberry Pi?
A: Yes, you can use the DFRobot_RaspberryPi_Board library available on GitHub, which supports this analog sound sensor via the ADC expansion board.
