Description

The Crowtail Sound Sensor module utilizes a simple electret microphone element to capture acoustic signals. The raw audio input is processed through a band-pass filter and amplified by an LMV358 operational amplifier, producing a stable analog voltage output that corresponds to the relative loudness of the detected sound. This design ensures a clean, conditioned signal suitable for direct ADC (Analog-to-Digital Converter) input on microcontrollers.

The module is engineered for easy integration into prototyping environments, featuring a standard Crowtail 4-pin interface that mates directly with compatible base shields. The on-board potentiometer allows fine-tuning of the sensor’s sensitivity and output baseline, enabling customization for different acoustic environments and detection thresholds.

Frequently Asked Questions

What is the operating voltage range for this sound sensor?

The module is designed for a strict 5V DC supply. Exceeding this voltage may damage the onboard LMV358 amplifier and the electret microphone element. Ensure your microcontroller or power source provides a stable 5V output.

How do I connect and read data from this analog sensor?

Connect the module's Crowtail cable to a compatible 4-pin port or wire the pins directly: VCC to 5V, GND to ground, and the signal (SIG) pin to an analog input pin on your Arduino or other microcontroller. Read the analog voltage value using the ADC; higher values indicate louder sound levels.

What does the on-board potentiometer adjust?

The potentiometer adjusts the gain and baseline output voltage of the LMV358 amplifier. Turning it allows you to set the sensor's sensitivity and the quiescent (no-sound) output level, which is useful for calibrating the detection threshold for your specific application environment.
