1. Introduzzjoni
This manual provides comprehensive instructions for the uxcell KY-002 SW-18015P Shock Vibration Sensor Module. This module is designed to detect vibrations and physical shocks, providing a momentary electrical signal when triggered. It is suitable for integration into various electronic projects, particularly those involving microcontrollers like Arduino.
2. Prodott Aktarview
The SW-18015P is a vibration switch that operates in an OFF (open circuit) state when at rest. Upon detecting an external force or vibration exceeding a certain threshold, its internal conductive pin momentarily closes (ON), completing a circuit and altering its electrical property. Once the external force subsides, the switch automatically returns to its open (OFF) state. This sensor is omnidirectional, meaning it can be triggered from any angle, enhancing its versatility.
It is specifically designed for small current trigger circuits and can be directly connected to a microcontroller's input/output (IO) port. The module features anti-interference capabilities and includes a fixed bolt hole for secure and easy installation.

5. Prinċipji Operattivi
The uxcell KY-002 SW-18015P module functions as a normally open (OFF) switch. In its quiescent state, the internal contacts are separated, resulting in an open circuit. When the module experiences a sufficient level of shock or vibration, the internal mechanism causes the contacts to momentarily touch, closing the circuit (ON). This change in state generates a digital signal (e.g., a momentary HIGH or LOW, depending on the pull-up/pull-down configuration) on the OUT pin, which can be read by a connected microcontroller. The omnidirectional design ensures that vibrations from various directions can effectively trigger the switch.
6. Applikazzjonijiet
This shock vibration sensor module is suitable for a wide range of electronic applications that require detection of physical impact or movement. Common applications include:
- Security systems (e.g., window/door vibration alarms)
- Impact detection in devices
- Motion-activated lighting or recording systems
- Tilt or orientation change detection
- DIY electronics projects requiring simple vibration sensing
7 Issolvi l-problemi
If the uxcell KY-002 SW-18015P module is not functioning as expected, consider the following troubleshooting steps:
- No Response to Vibration: Verify all electrical connections are secure and correctly wired (VCC, GND, OUT). Ensure the power supply voltage is within the specified range (up to 12V). Confirm that the vibration or shock applied is sufficient to trigger the internal switch mechanism.
- Triggers Foloz: Check for loose connections or unstable mounting. Excessive ambient vibrations or electrical noise might also cause false triggers. Ensure the module is mounted firmly.
- Riżultat Żbaljat: If using a microcontroller, review your code to ensure the digital input pin is correctly configured to read the sensor's output.
8. Manutenzjoni
The uxcell KY-002 SW-18015P module is designed for durability and requires minimal maintenance. To ensure optimal performance and longevity:
