+# Description
+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.
+
+## Usage Scenarios
+
+(Academic Papers) Automatically measure the noise of devices noise if multiple data points are needed.
+
+(Environmental monitoring) Monitoring the surrounding noise level.
