Decibel meters are used in several types of measuring instruments.
WS1361C is a cheap decibel meter that provides software interfaces to record surrounding noise level automatically.
Meanwhile, it also provides an interface for calibration to make sure the data is meaningful.
The sample rate is 1 per second.
Besides, I found that the data read from software has a one-second latency.
Be aware of the latency when using.
