Description: 1. Tap Sensor Module is an IoT component designed to detect and measure physical taps or strikes. It converts mechanical energy into electrical signals. 2. Components: The module typically includes a sensitive piezoelectric crystal sensor, signal conditioning electronics, and communication interfaces (e.g., I²C, SPI, UART). 3. Features: Small form factor, lightweight, low power consumption, high sensitivity, adjustable threshold, and waterproof options are common features of tap sensors. 4. Applications: Widely used in various applications such as smart furniture (e.g., chairs, beds), door/window monitoring systems, touchless buttons, and industrial machinery for condition monitoring and control. 5. Interfacing: Tap sensor modules can be interfaced with microcontrollers or single-board computers using standard communication protocols like I²C, SPI, or UART to transmit data in real-time. 6. Customization: Some tap sensors offer adjustable sensitivity levels and threshold settings,
