DFRobot SEN0232 Gravity: Analog Sound Level Meter

DFrobot SEN0232 Gravity: Analog Sound Level Meter is a basic instrument for measuring the noise or sound level of the surrounding environment. This sound level meter is Arduino compatible and supports plug and play interface. The SEN0232 Gravity: analog sound meter measures sound levels between 30dBA to 130dBA measuring range with a ±1.5dB measuring error. This sound level meter features an instrument circuit and low noise microphone that exhibits highly accurate sound level measurement.

The DFrobot analog sound level meter operates at a 3.3V to 5V input voltage range. This sound level meter offers linear relation between decibel values and the output voltage for straightforward conversion. Typical applications include environmental noise monitoring, highway noise monitoring, and room noise monitoring.
