**SW420 Vibration Sensor - High Sensitivity Vibration Alarm Module**

**Overview**
The SW420 Vibration Sensor is a highly sensitive vibration detection module designed for various applications such as theft alarms, smart cars, earthquake detectors, and motorcycle security systems. This module ensures reliable performance with its clean signal output and wide operating voltage range.

**Key Features**
- **High Sensitivity**: Detects even the slightest vibrations, ensuring timely alerts.
- **Wide Voltage Range**: Operates smoothly between 3.3V and 5V, compatible with most devices.
- **Clean Signal Output**: Provides stable digital switching outputs (0 and 1) for seamless integration.
- **Long Trigger Time**: Longer trigger duration compared to traditional vibration sensors, enhancing reliability.
- **Easy Installation**: Includes a fixed bolt hole for convenient mounting.

**How It Works**
When the product is stationary, the vibration switch remains closed, outputting a low signal (green LED lights up). Once the product vibrates, the switch instantly opens, outputting a high signal (green LED turns off). This allows you to connect the output directly to a microcontroller to monitor vibration levels and trigger alarms accordingly.

**Technical Specifications**
- Operating Voltage: 3.3V-5V
- Output Form: Digital Switching Outputs (0 and 1)
- Driving Ability: Over 15mA
- Comparator: Wide Voltage LM393
- Polarity Protection: Reverse polarity protection prevents damage to the chip.
