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
Objectives
- 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
- 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 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
- 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 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.
//
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
}
