Proposal: Development of a Library Noise Alert System Using Arduino

This proposal outlines the development of a library noise alert system using an Arduino microcontroller. This system will monitor noise levels and alert users when the noise exceeds a predefined threshold, promoting a quiet and conducive environment for study and research.

 

 Introduction

 This proposal outlines the development of a library noise alert system using an Arduino microcontroller. This system will monitor noise levels and alert users when the noise exceeds a predefined threshold, promoting a quiet and conducive environment for study and research.

 

Objectives

 - Design and build a system that can detect and alert users to excessive noise levels in a library.

- Select and integrate an Arduino board, noise sensor, speaker, memory card, and memory card reader.

- Develop and implement control software on the Arduino to monitor noise levels and trigger alerts.

- Provide a method for logging noise level data to a memory card for analysis.

 

Materials

 - Arduino Uno (or compatible board)

- Noise Sensor (e.g., Sound Sensor Module)

- Speaker

- Memory Card Module

- Memory Card

- Breadboard and Jumper Wires

- Enclosure for the system

- Additional components (e.g., resistors, capacitors)

 

Hardware Design

 - The noise sensor will be used to detect ambient noise levels in the library.

- The Arduino board will process data from the noise sensor and control the speaker to emit alerts.

- The memory card module will store noise level data for later analysis.

- All components will be mounted securely in an enclosure that allows sound to be detected and alerts to be heard clearly.

- A power source, such as a battery pack or USB power supply, will provide power to the entire system.

 

Software Development

 - Arduino IDE will be used to program the Arduino board.

- The code will continuously monitor noise levels via the noise sensor.

- When the noise exceeds a predefined threshold, the Arduino will trigger the speaker to emit an alert.

- The system will log noise level data to the memory card, including timestamps, for later analysis.

 

System Integration

 - The noise sensor will be connected to an analog input on the Arduino.

- The speaker will be connected to a digital output pin, with appropriate amplification if necessary.

- The memory card module will interface with the Arduino via SPI protocol.

- The Arduino will be programmed to handle sensor readings, trigger alerts, and log data.

 

Expansion and Future Work

 - The system can be enhanced by incorporating additional features such as:

  - Multiple noise sensors for wider coverage and more accurate monitoring.

  - A display to show real-time noise levels and alerts.

  - Integration with a mobile app or web interface for remote monitoring and control.

  - Advanced data analysis tools to identify noise patterns and optimize the alert threshold.

 

 Code

 

// Library Noise Alert System

// Detects noise levels and triggers a buzzer alarm

 

const int soundSensorPin = A0; // Connect the sound sensor to analog pin A0

const int buzzerPin = 9;      // Connect the buzzer to digital pin 9

 

void setup() {

  pinMode(buzzerPin, OUTPUT);

  Serial.begin(9600);

}

 

void loop() {

  int noiseLevel = analogRead(soundSensorPin); // Read analog value from sound sensor

  Serial.print("Noise Level: ");

  Serial.println(noiseLevel);

 

  // Adjust the threshold value based on your environment

  int threshold = 500; // Example threshold value

 

  if (noiseLevel > threshold) {

    // Noise detected! Activate the buzzer

    digitalWrite(buzzerPin, HIGH);

    delay(1000); // Buzzer duration (1 second)

    digitalWrite(buzzerPin, LOW);

  }

 

  // Add a delay to prevent continuous triggering

  delay(100); // Adjust as needed

}
