Specifications
- Spring-based vibration switch
- Digital output with adjustable sensitivity
- 3.3-5V supply
- Indicator LED
- Non-directional — responds to shake from any axis
What you can build with the SW-420 Vibration / Knock Sensor
- Tamper and intrusion detection
- Knock-to-activate switches
- Machine running/stopped detection
- Earthquake and impact triggers
