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 CH340G.
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.
Type: Normally closed
Working voltage: 3.3V to 5V
Output form: Digital switch output (0 and 1)
1. Product no vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit;
2. Product vibration, the vibration switch instantaneous disconnection, output the output high level, the green light is not bright;
3. 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.
