Detailed Product Description:

Enhance your projects with precise movement and impact detection using the versatile Vibration Sensor Module – Shock Detection Sensor. These modules are designed to reliably sense vibrations, shocks, and sudden movements, making them indispensable for a wide array of applications from security systems to industrial monitoring. Whether you're looking for simple event detection or more nuanced vibration analysis, there's a module to suit your needs.

Commonly featuring a sensitive SW-420 (normally closed type) or an 801S (metal spring-type) vibration sensor, these modules detect physical disturbances. When a vibration or shock occurs, the internal mechanism (e.g., a rolling ball or spring contact) momentarily changes its state, triggering an electrical signal. Many modules incorporate an onboard comparator (like the LM393 IC) and an adjustable potentiometer, allowing you to fine-tune the sensitivity threshold. This means you can decide exactly how much vibration is needed to trigger an output, preventing false alarms from minor disturbances.

These modules typically operate on a low voltage range of 3.3V to 5V DC, making them directly compatible with popular microcontrollers such as Arduino, Raspberry Pi, ESP8266, and ESP32. They often provide a digital output (HIGH/LOW), which is simple to interface with any digital input pin on your microcontroller. Some advanced versions might also offer analog output for more detailed vibration intensity measurement. With their compact size, low power consumption, and integrated status LEDs (indicating power and detection), Vibration Sensor Modules are cost-effective and easy-to-integrate solutions for building security alarms, smart doorbells, impact detection systems for parcels, car anti-theft devices, or even basic earthquake detection systems right here in Pune, Maharashtra, India, and beyond.

The Vibration Sensor Module is designed to detect mechanical vibrations, shocks, or sudden movements using a spring-type or piezoelectric sensor. It outputs a digital HIGH signal when vibration is detected, making it easy to interface with Arduino, NodeMCU, Raspberry Pi, and other platforms.

This sensor is ideal for applications such as security alarms, knock sensors, smart parking systems, industrial machinery monitoring, and more. The module features an onboard comparator, adjustable sensitivity via potentiometer (in some versions), and status indicator LEDs.
