KY031 Knock Sensor Module

The Knock Sensor Module is a compact vibration and impact detection module designed to detect knocking, tapping, vibration, and mechanical impacts. It uses a sensitive spring-based vibration sensor to detect physical movement and provides a digital output that can be easily interfaced with Arduino, ESP32, Raspberry Pi, and other microcontroller boards. The module features a simple 3-pin interface (S, +, -) for easy connection and is suitable for DIY electronics, vibration monitoring, security systems, knock detection, and automation projects. Features: Sensitive knock and vibration detection Detects tapping, shaking, and mechanical impacts Simple 3-pin interface: S, +, - Compact and lightweight design Easy to interface with microcontroller boards Suitable for Arduino, ESP32, Raspberry Pi, and DIY projects Applications: Knock and tap detection Vibration monitoring Security and anti-tamper systems DIY Arduino projects Automation and smart control systems Impact and movement detection Package Includes: 1 × Knock Sensor Module
