Features:
This is a commonly used knock module sensor that uses the SW-2802 vibration switching element. The SW-2802 vibration switching element is a spring type vibration induction trigger switch. The vibration switch is in an open state when it is at rest. When the external force is touched to reach the corresponding vibration force, or when the moving speed reaches an appropriate distance (bias), The conductive pin will instantly turn on the ON state; when the external force disappears, the switch will return to the open OFF state.; When it disappears, the switch returns to the open circuit OFF state. The sensor uses the characteristics of components to build a circuit to convert the vibration signal into a high-low level conversion signal.
The sensor is compatible with various microcontroller control boards, such as the for Arduino series of microcontrollers. When using it, we provide a method for using this sensor with the Arduino series of microcontrollers.
The sensor comes with a 2.54mm anti-reverse plug-in white terminal. When in use, we can connect to the MCU with DuPont cable. To facilitate wiring, we also specially designed an expansion board that is fully compatible with this sensor and the Arduino UNO R3 microcontroller. We only need to stack the expansion board to the UNO R3 MCU, and use a 3P double-head XH2.54 plug wire (anti-reverse) to connect to the expansion board, which is simple and convenient.
