1, the company produced a closed static vibration sensor
2, the output comparable, the signal is clean, the waveform is good, the capacity of the strong drive exceeds 15mA
3. The working voltage is 3.3V-5V
4, Output model: digital switch output (0 and 1)
5. Fixed bolt hole for easy installation
6, Small PCB Board Size: 3.2cm x 1.4cm
7. Using the LM393 wide voltage comparator
For a variety of vibration triggering actions, reported theft alarm, smart car, earthquake alarm, motorcycle alarm, and so on.
Compared with the fixed opening vibration sensor unit, this unit has a longer vibration trigger, which can drive the relay unit
Unit Instructions for Use:
1, the product does not vibrate, the vibration switch is the conduction state closed, the output is low level, the green LED light.
2, the product vibration, the switch vibration is instantaneous disconnection, the output level is high, the green indicator is not bright.
3, the output can be directly connected with the computer single-chip, through the computer single-chip to detect the high-low level, so as to detect whether the environment has a vibration, alarm effect
