About this item

The ELECROW Crowtail-Knock Sensor is a compact, digital piezoelectric sensor designed to detect vibrations or knocks. Utilizing the KY-031 sensor module, it generates a small voltage pulse when subjected to mechanical stress, making it ideal for applications like touch-sensitive interfaces, security systems, or interactive projects. This sensor features a digital Crowtail connector, ensuring easy integration with Crowtail-compatible boards, such as the Crowduino or Arduino, without the need for breadboards or jumper wires. It operates at a 5V power supply and outputs a digital signal indicating the presence of vibration. The module is particularly useful in scenarios where detecting physical interactions is essential. Its small form factor allows for seamless integration into various projects, from DIY electronics to educational kits.
