What is a Vibration Sensor?
A vibration sensor’s other name is a piezoelectric vibration sensor. Notably, the sensor works by measuring the pressure, acceleration, and changes in the vibration of a system.
With the help of vibration sensor modules, these wireless sensors function with the accompaniment of a Raspberry Pi or an Arduino. As a result, this property allows the sensor applications to have a smaller but accessible form factor.

What are the Types of Vibration Sensors?
- Eddy current
The eddy current sensor efficiently works on large objects by producing magnetic fields. As a result, these magnetic fields then detect the position change of a magnetic component. This sensor is also known as a capacitive displacement sensor.
- Velocity sensor
This sensor type senses high temperatures. Importantly, it uses a current produced by a magnet in a coil for its sensing. Also, velocity sensors are reliable since they are less susceptible to overloads of the amplifier, unlike the gyroscope sensors.
- Strain gauge sensor
This type of sensor works by measuring any strain on a machine tool. After that, it converts the change into electrical resistance. Notably, the music it estimates can be pressure, tension, or weight. Also, this sensor efficiently works on curved surfaces.
- Piezoelectric accelerometer sensor
The piezoelectric accelerometer sensor is a very suitable sensor for various applications. This is because the sensor is versatile and has a wide dynamic range. As a result, these sensor properties support many applications, such as security alarms.

Things to Consider When Choosing a Vibration Sensor.
- Frequency
Significantly, the vibration frequency affects the measurement accuracy of what a sensor will detect. In a wireless vibration sensor, the frequency is the percentage error allowed over a complete measurement range of a system.
- Measuring and dynamic range
A broader dynamic and measuring range allows for adequate measurement.
- Sensitivity
Lower amplitude vibrations support a higher sensitivity sensor and vice versa. However, the g level, which is the peak, should not exceed the range of acceleration of a wireless vibration sensor. If the g level exceeds the acceleration range, there will be signal distortion and amplifier overload.
- Environmental conditions of usage
Environmental conditions determine the durability of a sensor. Therefore, if these conditions are high, industrial sensors are ideal.
