Why does the accelerometer read zero G's when it's in free fall?

All accelerometers are used to measure increasing or decreasing acceleration, and they can detect vibration because it is a change in acceleration between multiple directions. Free fall, by definition, is a static acceleration, which means the object may be moving, but its acceleration is not changing at all. SDI’s MEMS DC accelerometer technology allows it to measure free fall because it doesn’t require any change of acceleration to supply data, and therefore it will report back 0g of acceleration.

My accelerometer appears to be broken. When I place it on the desk with the lid facing up, it reads +1G. How do I fix this?

SDI’s MEMS DC accelerometers are designed to respond to the Earth’s gravity. If you are on Earth, then you are in a +1g gravitational field. Turn the device over and you will see a -1g reading, which you can use to perform your own bias calibration of the device. Visit our Technology page to learn more about how SDI’s accelerometers work. Also see the How to Calibrate Your Accelerometer page for how to use this feature for self-calibration.

Do I need a charge amplifier or signal conditioning to use my Silicon Designs MEMS DC accelerometer module?

All Silicon Designs MEMS DC accelerometers feature integrated amplifiers, so an additional one is not required. Signal conditioning is optional.

Are Silicon Designs plug-&-play MEMS DC accelerometer modules waterproof? What is their IP designation?

While all modules are considered weatherproof, only Models 2240 and 2480 may be used while submerged. We recommend the protection of the connector from exposure. Please Contact Us prior to use, and we’ll walk you through the process. The IP designation of the other modules is IP61.

I am using my plug-&-play module in single-ended mode. What should I do with the unused wire?

Leave the wire disconnected. Do not connect the unused wire to ground, as you will overheat the device and cause premature accelerometer failure.

Calibrate Your SDI Accelerometer

One benefit to SDI’s accelerometers is they respond to gravity, which allows you to perform a 1G flip to check your accelerometer’s calibration anytime, anywhere.

Measure Tilt

SDI’s 2G accelerometers are very sensitive and have exceptionally low noise, two qualities that make measuring tilt possible with just a little math.
