SW1801P vibration/tilt sensor module

• The comparator output, the signal clean, good waveform, driveability, more than 15mA.
• The working voltage of 3.3V-5V
• With a fixed bolt hole, easy to install
• Using a wide voltage LM393 comparator

Pin Description :

1. VCC: Connect the power supply positive
2. GND: Connect the power supply negative
3. DO: Digital signal output
4. AO: Use this vibration sensor to disable this function

Module instructions:

1. the product does not shake, the vibration switch was disconnected, the output high, Greenlight does not light;
2. the product vibration, the vibration switch instantaneous conduction, the output low, green light;
3. the output can be directly connected with the microcontroller, through the microcontroller to detect high and low levels, which to detect whether the environment vibration, play a warning role.

Use:

For a variety of vibration trigger, reported Pao alarm, intelligent car, electronic building blocks and so on.
Please note that this module in the induction of a small shock when the trigger time will be very short, not enough to drive the relay, some people can directly connect with the relay module data, the actual use of poor results.
