Module  use:

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.

Module Description:

1. Use of the company’s high sensitivity vibration switch SW-18010P default with vibration sensors.
2. The comparator output signals clean, good waveform, driving ability, than 15mA.
3. Working voltage of 3.3V-5V.
4. The output form: 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.

1. VCC: positive power supply
2. GND: negative one
3. DO: digital signal output
4. AO: With this shock sensor this function is invalid
