SW-420 Vibration Sensor
The Vibration module based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can be adjusted by the on-board potentiometer.
When this no vibration, this module output logic LOW the signal indicate LED light,And vice versa.
Application Idea
- Vibration detecting
- Burglary protection system
- The default state of the swith is close
- Digital output
- Supply voltage:3.3V-5V
- On-board indicator LED to show the results
- On-board LM393 chip
- Dimension of the board: 3.2cm x 1.4cm
