Sound Warning

This is Warning device When the sound exceeds the set level. The KY-037 is a voice receiver. And exported with ISD-1820 and BUZZER. The ISD-1820 is a voice recorder and plays if configured to match KY-037 and Set KY-037 to analog because analogue is a measurement that can measure the sound, which is different from the digital values ​​can be measured only 0 and 1.

Steps

  • Step 1

Let's check the sound value. If the sound turns on, the LED will turn on.

  • Step 2

Add the buzzer and check the sound value together. If the sound turns on

  • Step 3

Add the sound recorder with check the sound value. If the sound turns on,the buzzer and recorder will turn on.

  • Step 4

Type code.

  • Step 5

Add the LED SWITCH 3 PRONG

  • Step 6

Complete arranging the components.

EXPANDED TECHNICAL DETAILS

Acoustic Threshold Safety Beacon

This project provides a professional-grade sound monitoring system that triggers a visual/acoustic alarm if environmental noise exceeds a healthy limit.

  • Pre-Amplified Microphone Analytics: Uses a high-gain sound sensor module. The Arduino captures the analog waveform and performs a "Peak-to-Peak" amplitude calculation every 100ms.
  • Programmable Decibel Threshold: Users can set the "Warning Level" via a physical potentiometer. The Arduino compares the noise floor to this limit and triggers an RGB LED or buzzer if the limit is breached for more than 2 seconds.

Prototyping

  • Verified with Arduino IDE: Optimized for rock-solid stability, with a software "Hysteresis Window" that prevents the siren from "Chirping" when sound is exactly at the limit.
