1/3/5Pcs SW-1801P Vibration Sensor Module High-Sensitivity Normally Open Alarm Switch Module for Security Applications

Description:

Product Features:

1. Employs a high-sensitivity vibration switch, using the SW-18010P vibration sensor by default.

2. Comparator output, clean signal, good waveform, strong driving capability exceeding 15mA.

3. Operating voltage 3.3V-5V.

4. Output type: Digital switch output (0 and 1).

5. Equipped with mounting bolt holes for easy installation.

6. Uses a wide-voltage LM393 comparator.

Package Included: 1/3/5Pcs

Applications: Used for various vibration triggering applications, burglar alarms, smart cars, electronic building blocks, etc. Please note that this module has a very short trigger time when sensing small vibrations, insufficient to drive a relay. Some documentation indicates direct connection to a relay module, but in practice, the effect is unsatisfactory.

Instructions for Use:

1. When the product is not vibrating, the vibration switch is in the off state, the output terminal outputs a high level, and the green indicator light is off.

2. When the product vibrates, the vibration switch momentarily conducts, the output terminal outputs a low level, and the green indicator light illuminates.

3. The output terminal can be directly connected to a microcontroller, which can detect high and low levels to detect whether there is vibration in the environment and thus serve as an alarm.

Notes:

Due to manual measurement , there may be 5mm deviation exist,hope you can understand.

There are slight difference between the picture and the item caused by light brightness,hope you can understand.
