The Grove - Loudness Sensor is designed to detect the loudness of environmental sound. Based on amplifier LM2904 and a built-in microphone, it amplifies and filters the high frequency signal that received from the microphone, and outputs a positive envelop. This will make for Arduino's signal acquisition. The output value depends on the level of sound input. In order to avoid unnecessary signal disturbances, input signal will go through two times filtering inside the module. Lastly, there is a screw potentiometer that enables manual adjustments to the output gain.
Grove compatible interface
Wide supply voltage range
Built-in signal filtering
Gain adjustable via screw potentiometer
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.

The maker says: Just the first time I saw children’s painting, had idea to create it in kind. Every stitch was completed by hand according painting. Especially, added some special functions that girl’s skirt could give out blue light and ...
Does it come with a cable?
is it possible to use it with 3.3V power? I am using a MSP430 micro controller that operates on 3.3 V. If not, is there another board that works with 3.3 V?
I bought this sensor.
And I could not know the principle of this sensor.
PLEASE SEND ME THE CIRCUIT OF THIS SENSOR.
AND PLEASE WRITE THE CAPACITANCE AND RESISTANCE.
Please help me~T.T
What is the difference between the Grove loudness sensor and the grove sound sensor?
Which would be better at detecting loud low sounds? (e.g. neighbor's truck)
