Description

There are various sound detection sensor modules available for Arduino-compatible intelligent vehicles. One commonly used module is the “Sound Sensor Module” or “Sound Detection Sensor Module.” Here’s a typical specification for such a module:

1. Operating Voltage: Most sound detection sensor modules operate within a voltage range of 3.3V to 5V, making them compatible with Arduino boards.

2. Sound Sensitivity: The module should have an adjustable sensitivity level to detect sound variations. It should be able to detect sounds within a specific frequency range, typically from around 50Hz to 20kHz.

3. Output Signal: The module usually provides a digital output signal that can be easily read by Arduino. It often has a digital output pin (e.g., D0 or D1) that goes HIGH when a sound is detected and LOW when no sound is present.

4. Indicator LEDs: Some modules have built-in LEDs to indicate the sound detection status, such as power ON, sound detected, and no sound detected.

5. Analog Output (optional): Some sound sensor modules also offer an analog output pin (e.g., A0) that provides a continuous voltage proportional to the sound level. This analog output can be useful for more precise sound level measurements.

6. Adjustable Sensitivity: The module may feature a potentiometer or a jumper to adjust the sound sensitivity level. This allows you to customize the threshold at which the module triggers a sound detection event.

7. Easy Integration: Sound detection modules are designed to be easily integrated with Arduino and other microcontrollers. They typically have standard 3-pin headers (e.g., VCC, GND, and output) for convenient connection.

8. Size and Form Factor: The module’s physical size and form factor should be compact and suitable for integration into an intelligent vehicle project.

It’s important to note that the specifications can vary depending on the manufacturer and specific module model. Therefore, it’s recommended to check the datasheet or product documentation provided by the manufacturer for detailed specifications and usage guidelines of a particular sound detection sensor module you intend to use.
