Technical summary
The SW-420 sensor module produces logic states according to the vibration and external force applied.
When there is no vibration, this module gives a logic low output, and when it senses vibration, the output goes to logic high.
The working voltage of this module is between 3.3V and 5V DC and it has a potentiometer to adjust the sensitivity.
Operating voltage: 3.3-5V
Output: Digital low / high 0/1
Current: 15mA
Uses an LM393 comparator
Size: Approx. 32x14mm / 1.26x0.55inch
