Vibration Sensor Blue Motion Tilt Switch Alarm Module Arduino PIC.
+ 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.
+ Normally closed type vibration sensor SW-420.
+ The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA.
+ Has a fixed bolt hole, convenient installation.
+ Use the LM393 wide voltage comparator.
+ Model: SW-420
+ Type: Normally closed
+ Working voltage: 3.3V to 5V
+ Output form: Digital switch output (0 and 1)
+ Size: 32 x 14mm / 1.26" x 0.55"
Module directions for use:
+ When the vibration switch is closed, the output terminal output low level, the green light is lit;
+ When the product vibration, the vibration switch instantaneous disconnection, the output terminal output high level, the green light is not bright;
+ Output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect whether there is a vibration environment, alarm alert.
