LED noise display screenFunction implementation:
Collect on-site noise and display the noise value in real-time on the LED display screen, and divide the noise value into 2 levels for display and processing (the level threshold can be set by oneself):
A quiet scene with a noise level of less than 60 decibels, the screen displays the noise value in green.
When the noise level on site is greater than 60 decibels and less than 70 decibels, the display screen will show the noise level in red font to alert the surrounding crowd.
