for a variety of triggering shock, reported theft alarm, intelligent car, electronic building blocks.
Please note that this module triggers a very short time upon sensing a big shock, not enough to drive the relay, the data show that some people can be connected directly to the relay module, the practical application ineffective.
1, the use of the company's high sensitivity vibration switch SW-18010P default with vibration sensors.
2, the comparator output signal clean, good waveform, driving ability, more than 15mA
3, the working voltage 5V-3.3V
4, output forms: 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 LM393
Module wiring instructions:
1.VCC: positive power supply
2.GND: negative one
3.DO: digital signal output
4.AO: With this shock sensor this function is invalid
1, when the product does 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 is turned 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 the environment there is vibration, play a role in the police
