Vibration Analog Sensor Products

Description

Vibration analog sensors respond to repetitive mechanical motion and output an analog voltage signal in order to measure the amount of vibration. The most common type of sensors that convert vibration to voltage are piezoelectric. The piezo element can convert vibration to voltage or voltage to vibration, which means that it can be used as either a vibration sensor or a buzzer speaker to play tones. Piezo elements are polarized, which means that voltage passes through them (or out of them) in a specific direction. They typically have a red wire for the higher voltage and a black wire for the lower voltage.

Piezo elements for vibration sensing applications have the potential to produce very large AC voltage spikes, ranging up to ±50V. A large 1MΩ (or higher) resistor connected in parallel to the piezo sensor can be used to load down the circuit. Microcontroller boards usually have some limited internal protection for negative voltages if the current is kept low. For example, the ATmega328 microcontroller used in the Arduino Uno R3 board has internal pin protection diodes that will clamp any over/under voltage to VCC+0.5V and GND-0.5V. However, exceeding these internal protections limits can potentially damage the microcontroller. Alternatively, Zener diodes and/or Schottky clamping diodes can be used to clamp voltages down to safe levels or OpAmps can be used to buffer the signal.

SparkFun Piezo Vibration Sensor - Large with Mass (SEN-09197)

SparkFun SEN-09197 Piezo Vibration Sensor - Large with Mass

Seller: SparkFun

Package includes:

1x Piezo Sensor

+ About this item:

Basic Piezo Sensor used for flex, touch, vibration, and shock measurements. Comes with solderable crimp pins and a mass attached to the tip. This mass increases the sensitivity to motion. A small AC and large voltage (up to ±90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels.
