The **F2VS-B1-R** is a specific electronic component, typically categorized as a **Vibration Sensor** or a **Tilt/Motion Switch**, often utilized in consumer electronics, automotive security, and industrial monitoring. --- ### 1. General Specifications The device is designed to detect mechanical vibration or changes in orientation. Below are the typical technical parameters for this class of component: | Parameter | Specification (Typical) | | :--- | :--- | | **Type** | Vibration / Tilt Sensor | | **Contact Type** | Normally Open (NO) / Ball-rolling mechanism | | **Max Voltage** | 12V - 24V DC | | **Current Rating** | ~2mA to 10mA | | **Operating Temp** | -25°C to +85°C | | **Mounting Type** | Through-hole (THT) or SMD (depends on suffix) | --- ### 2. Internal Mechanism The "B1" series usually employs a **ball-rolling mechanism**. Inside the gold-plated or sealed housing: * **Conductive Balls:** Two or more small metal balls sit within a cavity. * **Triggering:** When the device is shaken or tilted beyond a specific angle (the trigger angle), the balls move to bridge two contact points. * **Output:** This completes an electrical circuit, sending a "High" or "Low" signal to a microcontroller (MCU). --- ### 3. Key Electronic Features * **Non-Mercury Design:** Unlike older tilt switches, the F2VS series is environmentally friendly and RoHS compliant. * **Omnidirectional Sensing:** Depending on the internal geometry, it can detect vibration from multiple axes. * **Low Power Consumption:** Since it acts as a passive switch until triggered, it is ideal for battery-operated devices. --- ### 4. Implementation Example To interface this part with a microcontroller (like an Arduino or ESP32), a pull-up resistor is required to prevent a floating state. ```cpp // Example: Detecting a vibration trigger const int sensorPin = 2; // Connected to F2VS-B1-R int sensorState = 0; void setup() { pinMode(sensorPin, INPUT_PULLUP); // Internal pull-up Serial.begin(9600); } void loop() { sensorState = digitalRead(sensorPin); if (sensorState == LOW) { Serial.println("Vibration/Tilt Detected!"); delay(100); // Debouncing } } ``` --- ### 5. Common Applications 1. **Anti-theft Alarms:** Detecting when a vehicle or stationary object is moved. 2. **Power Management:** "Wake-up" sensors for remote controls or toys to save battery. 3. **Safety Shut-off:** Turning off heaters or irons if they tip over.
