About this item

The ELECROW Crowtail‑Sound Sensor is a compact and cost‑effective module designed to detect ambient sound levels. It utilizes a microphone to capture sound signals, which are then processed by a band‑pass filter and amplified using an LMV358 operational amplifier. This setup allows the sensor to output an analog voltage corresponding to the relative loudness of the detected sound. The module is equipped with a potentiometer that enables users to adjust the sensitivity of the sensor, making it versatile for various applications. It is compatible with the Crowtail interface, allowing for easy integration with development boards such as Arduino, Raspberry Pi, and ESP32. The sensor is ideal for projects involving sound detection, noise level monitoring, and interactive installations where audio input is required.
