Description
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
Description:
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.
