Construction Noise Monitor

About this project

Build a real-time construction site noise level monitoring system using analog sound sensor and Arduino Uno. Measure ambient noise in decibels (dB), classify noise zones per CPCB standards (Residential, Commercial, Industrial, Silence), and display on 16x2 LCD with LED bar graph visualization. Implement automatic alerts when noise exceeds permissible limits for environmental compliance and worker safety monitoring.
