Specification:
1. Weight: 8g;
2. The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma;
3. The working voltage is 3.3V to 5V;
4. Output form: digital switch output (0 and 1);
5. Has a fixed bolt hole, convenient installation;
6. Small board PCB size: 3.2cm x 1.4cm;
7. Use the LM393 wide voltage comparator.
Detail:
1. Used to trigger the effect of various vibration, theft alarm, intelligent car, earthquake alarm, motorcycle alarm, etc;
2. This module is compared with the normally open type vibration sensor module, vibration trigger for longer periods of time, can drive the relay module.
Module directions for use:
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 micro controller, through single chip microcomputer to detect the high and low level, thus to detect whether there is a vibration environment, call the police.
