MMA8652

Hello

I am looking for a sensor in order to detect chocks and freefall of a 15Kg electronic box
The electronic contains a MPU but we want to be able to detect even when the system is in standby.
Which product in your catalog do you advise me ?
I was looking at MMA8652, do you think it could fit ?

Hello,

Hi,

MMA8652 would be a great selection for your application, you can send the accelerometer into sleep mode and set it to wake and measure when there are movement events.

Plus with the Freefall and Motion embedded functions of the MMA8652, would fit perfectly into your application requirements.

You can find all the documentation available for this accelerometer in the following link: https://www.nxp.com/products/sensors/motion-sensors/accelerometers-for-iot/2g-4g-8g-low-g-12-bit-digital-accelerometer:MMA8652FC?tab=Documentation_Tab

Have a great day,
Jose

Thank you Jose

I select MMA8652, and PCB routing is taking it in account.

Hi JC,

Glad to know that you selected the MMA8652.

In case you want a lecture, there is an application note (AN1902) that provides guidelines for the handling and board mounting of QFN and SON (DFN) packages including recommendations for printed-circuit board (PCB) design, soldering, and rework. You can find this application note in the following link: https://www.nxp.com/docs/en/application-note/AN1902.pdf

Have a great day,
Jose
