Introduction
A vibration sensor is a device that detects the magnitude and frequency of vibration in a system. We may utilize vibration sensors to provide maintenance teams with insight into situations within important assets that could contribute to equipment failure, allowing them to forecast machinery maintenance, minimize overall costs, and improve machine performance. This article is about the KY-002 vibration sensor
Hardware Overview of KY-002 Vibration Sensor
A conductive wire coil is enclosed inside the plastic casing of the KY-002 Vibration Shock Sensor. The coil bends and touches an electrode when the sensor is jolted, allowing current to flow between the coil and the electrode.
There is a black tube that you can see outside the sensor. A metal spring connected to the ground wrapped around a metal rod connected to a positive voltage within that black tube. When the spring bends because of a powerful jolt or vibration, it contacts the rod, allowing current to flow between the rod and the spring.
Features
- Capacitive Vibration Sensor
- Omnidirectional, Vibration from any angle can trigger the sensor.

Applications of Vibration Sensor
Earthquake Monitoring System
We can measure earthquakes by using a vibration sensor, that detects the vibrations generated by seismic waves. These waves can be natural because of earthquakes or can be produced b by some human activities.
