Minisense 100 Piezo Vibration Sensor


SKU: SEN-034 Category:


Feature Highlights:
-High Sensitivity
-Good Frequency Response
-Excellent Linearity
-Shielded Construction
-Analog Output
-Withstands High Shock
-Comes with mass

The Minisense 100 is a low-cost cantilever-type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. The pins are designed for easy installation and are solderable.
Horizontal and vertical mounting options are offered as well as a reduced height version. The active sensor area is shielded for improved RFI/EMI rejection. Rugged, flexible PVDF sensing element withstands
high shock overload. Sensor has excellent linearity and dynamic range, and may be used for detecting either continuous vibration or impacts. The mass may be modified to obtain
alternative frequency response and sensitivity selection (consult factory).

This sensor is Arduino/Saleng Uno/Mini compatible. It outputs an analog voltage high enough for most microcontroller ADC’s. If you expect high vibrations then you may want to insert a 5.1V zener across to protect your analog input.

Here is a simple test code to display raw ADC readings below 5V on the serial monitor. Connect the + pin to the Arduino’s A0 and – pin to the GND of the Arduino. Do not forget to connect a 5.1V zener across the sensor.
