For a variety of shock triggering effect, reported theft alarm, smart car, electronic building blocks and so on.
Please note that this module will trigger a short time when the small vibration sensor, enough to drive a relay, some of the information and relay modules can be connected directly to the practical application of the results are poor.
1, the use of the company's various sensitivity vibration switch, default by SW-18010P vibration sensors.
2, the comparator output signal clean, good waveform, driving ability, than 15mA
3, the working voltage of 3.3V-5V
4, the output format: digital switching output (0 and 1)
5, a fixed bolt holes for easy installation
6, a small PCB board size: 3.2cm x 1.4cm
7, using a wide voltage comparator LM393
Module for use:
1, when the product is not shock, vibration switch OFF state, the output of high output, the green light does not shine;
2, when the product is shock, vibration switch turns on instantly, output of low output, the green indicator light;
3, the output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting whether there is vibration environment, the role played alarm
