Description
Purpose:
For a variety of motion trigger action, reported theft alarm,
intelligent car, earthquake alarm, motorcycle alarm.
This module with normally open type shock sensor module compared to
shake trigger longer can drive relay module
Module Features:
1, the use of the company\'s SW***0 vibration sensor normally
closed.
2, the comparator output signal clean, good waveform, driving
ability, than *5mA
3, the working voltage 3.3V*5V
4, the output format: Digital switching output (0 and 1)
5, a fixed bolt hole for easy installation
6, small PCB board size: 3.2cm x 1.4cm
7, using a wide voltage comparator LM**3
Module for use:
1, when the product does not shock, vibration switch was closed
conductive state, output of low output, the green indicator
light;
2, when the product is shock, vibration switch instantly turned
off, the output-side output high, green light does not shine;
3, the output can be directly connected to the microcontroller
through the microcontroller to detect high and low, thereby
detecting whether the environment there is vibration, play a police
role
