Product Description

SW-420 Normally Closed Type Vibration Sensor Module 3.3V-5V Alarm Sensor Module Suit for Anti-Theft/ Earthquake/Motorcycle Alarm

Feature:

1.Wide Application Range:This module is suitable for various applications that require vibration triggering, such as anti-theft alarms, smart cars, earthquake alarms, motorcycle alarms, and more. Its versatility makes it a valuable addition to different projects.
2.Extended Vibration Triggering Time:Compared to other models, this vibration sensor module offers a longer duration of vibration triggering. It ensures that the module remains responsive for an extended period, allowing for accurate detection and reliable performance.
3.Clean Signal with Strong Driving Capability:The module utilizes SW-420 normally closed vibration sensor produced by our company. It features a comparator output, which provides a clean signal with a good waveform. The module has a strong driving capability of over 15mA, enabling effective signal transmission.
4.Digital Switch Output:This module provides a digital switch output in the form of 0 or 1. When there is no vibration detected, the vibration switch remains closed, and the output terminal generates a low-level signal. The green indicator light illuminates. On the other hand, when vibration occurs, the switch momentarily opens, and the output terminal generates a high-level signal. The green indicator light turns off.
5.Convenient Installation:The module is designed with fixed bolt holes, making it easy to install and integrate into various setups. These pre-drilled holes ensure secure mounting and stability during operation.

 

Specification:
Origin: Mainland China
Type: Module
Condition: New
1. Working voltage 3.3V-5V
2. Small board PCB size: 32mm x 14mm
Module Features:
1. Adopt the SW-420 normally closed vibration sensor produced by our company.
2. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA
3. Output form: digital switch output (0 and 1)
4. There are fixed bolt holes for easy installation

Module usage instructions:
1. When the product does not vibrate, the vibration switch is in a closed conduction state, the output terminal outputs a low level, and the green indicator light is on;
2. When the product vibrates, the vibration switch is disconnected instantly, the output terminal outputs a high level, and the green indicator light is off;
3. The output terminal can be directly connected to the single-chip microcomputer, and the high and low levels can be detected through the single-chip microcomputer, so as to detect whether there is vibration in the environment and play an alarm role
use:
It is used for various vibration triggers, theft alarm, smart car, earthquake alarm, motorcycle alarm, etc.
Compared with the normally open vibration sensor module, this module has a longer vibration trigger time and can drive the relay module

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
