Description:
The KY-002 Vibration Switch Sensor Module is designed to detect vibrations, shocks, or sudden movements, making it ideal for applications requiring motion sensing or impact detection. At its core, the module features a conductive spring mechanism that, when subjected to external force or shaking, closes the circuit momentarily, sending a digital signal to the connected microcontroller. This simple yet effective design allows for easy integration with various platforms, including Arduino, ESP32, and Raspberry Pi, enabling projects such as anti-theft alarms, motion-activated devices, and equipment monitoring systems.
Operating at a standard 3.3V or 5V DC, the KY-002 module is straightforward to interface with digital input pins of microcontrollers. Its compact form factor and minimalistic design, comprising a vibration switch and a pull-up resistor, ensure low power consumption and reliable performance. The module is omnidirectional, meaning it can detect vibrations from any angle, enhancing its versatility in different project setups. Whether for educational purposes or practical implementations, the KY-002 offers a cost-effective solution for incorporating vibration detection into electronic projects.
