Sensor Recommendation for Vibration and Motion Detection

[Jayk]

Hi,

 

We are developing a product/device that is mounted on a machine/vehicle that generates vibrations when in the ON state. We need a sensor that can

 

1.. Detect vibration start and stop while the device is stationary, with good accuracy, to determine when the machine is ON and for how long.

2. Differentiate between vibration and actual motion, meaning it should detect when the device is no longer stationary and has started moving in any direction in on condition with vibration.

3. Detect motion in the OFF state, where the machine is off (no vibration), but the device itself has started moving and trigger an interrupt to alert the MCU.

 

Note: We can measure and predefine the acceleration threshold that should be considered as vibration.

 

Is there a sensor with an internal mechanism that can directly provide output to differentiate between vibration and motion?

 

Thanks,

 

Jay

You might be looking for an Accelerometer and Gyroscope sensor. Try searching.

The design logic is quite correlated to your application using an Accelerometer and Gyroscope sensor. You might want to use some open source code as a base for your application development. Try searching it, too.

There are some Accelerometer and Gyroscope sensor modules as electrical LEGO bricks, based on which you could build a prototype quickly.

yes, i want specific sensor as suggestion, and already described my use case i didn't have expertise on Which is best fit for my application. that's why i need your input for our low power application.

Try MPU6050 or MPU9250 from TDK. There also some modules built with these chips and some Arduino Libs are available.

This is an ST forum and one should recommend ST products.
