The **VS-K6-R** is a specific electronic component, typically categorized as a **Vibration Sensor** or a **Piezoelectric Transducer**, often used in security systems, industrial monitoring, and consumer electronics to detect mechanical stress or movement. --- ### 1. Key Technical Specifications The following table outlines the general electronic characteristics of the VS-K6-R series: | Parameter | Typical Value | | :--- | :--- | | **Component Type** | Piezoelectric Vibration Sensor | | **Resonant Frequency** | 6.0 kHz ± 0.5 kHz | | **Resonant Impedance** | ≤ 500 Ω | | **Capacitance** | 10,000 pF ~ 15,000 pF (at 120Hz) | | **Operating Temperature** | -20°C to +70°C | | **Material** | Lead Zirconate Titanate (PZT) / Brass or Stainless Base | --- ### 2. Functional Description The VS-K6-R operates on the **Piezoelectric Effect**. When the ceramic element is subjected to mechanical vibration or pressure, it generates a small proportional electrical voltage. * **Sensitivity:** It is highly sensitive to high-frequency vibrations near its 6kHz resonant peak. * **Output Type:** Analog voltage signal (requires amplification or a comparator circuit for digital processing). * **Form Factor:** Usually a thin, circular diaphragm designed to be mounted flush against a surface. --- ### 3. Common Applications The VS-K6-R is widely integrated into the following systems: 1. **Security Alarms:** Detecting glass breakage or forced entry on doors and windows. 2. **Industrial Maintenance:** Monitoring motor bearings for abnormal vibration frequencies. 3. **Consumer Electronics:** Used as a "knock" sensor or a simple acoustic pickup (microphone) for low-fidelity audio triggers. 4. **Automotive:** Detecting engine knock or structural impacts. --- ### 4. Basic Interface Circuit To use the VS-K6-R with a microcontroller (like an Arduino or ESP32), a simple conditioning circuit is required: ```cpp // Logic for a basic vibration threshold trigger int sensorPin = A0; // Connected to the output of an Op-Amp circuit int threshold = 500; void setup() { pinMode(sensorPin, INPUT); } void loop() { int val = analogRead(sensorPin); if (val > threshold) { // Trigger alarm or action } } ```
