Module Vibration Tilt Sensor SW-420
This is a normally closed alarm sensor module.
Used to trigger the effect of various vibration, theft alarm, intelligent car, earthquake alarm, motorcycle alarm, etc.
This module is compared with the normally open type vibration sensor module, vibration trigger for longer periods of time, can drive the relay module.
The comparator output waveform has driving ability for more than 15 ma .
The working voltage 3.3V to 5V
Output form: Digital switch output (0 and 1)
Onboard LM393 wide voltage comparator
Module directions for use:
When there is no vibration , the switch is in closed state.The output is at low level, the green light glows.
When there is vibration, the vibration switch instantaneously disconnects.The output goes to high level.The LED goes off.
The output can be directly connected to microcontroller,to detect the high and low level, thus to detect whether there is a vibration .
