Description: The ADXL377 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned analog voltage outputs that has a full-scale range of ±200g for measuring more extreme changes in motion, shock or vibration. This board has broken out all the pins you’ll need to get the necessary data from the accelerometers. The breakout is perfect for applications like concussion and head trauma detection or high force event detection.

Getting the ADXL377 Breakout set-up is easy. Simply supply the accelerometer with power (3.3V and GND), then hookup the X, Y, and Z lines of the sensor to ADC pins on your chosen development board and you will be good to go. Bandwidths can even be selected to suit the needed application, with a range of 0.5 Hz to 1600 Hz for X and Y axes and a range of 0.5 Hz to 550 Hz for the Z axis.

It should be noted that this breakout has a maximum voltage of 3.6V. Fortunately, you won’t need a lot of power to make the accelerometers work. In normal operating mode they typically draw about 300 µA.

Features:

  • Operating Voltage: 1.8V - 3.6V
  • Typical Current: 300 μA
  • Range: ±200g
  • 3-axis sensing
  • Bandwidth adjustment with a single capacitor per axis
  • 4x Mounting Hole

Customer Comments

  • I’m not sure the product page here is accurate. The datasheet appears to indicate that the bandwidth of the X and Y axes are up to 1300Hz and the bandwidth of the Z axis is up to 1000Hz.

  • Can I use this accelerometer to detect when something goes upside-down or on its side it turns on an led light?

    • The sensing range may not be precise enough for small movements like that to get a reliable reading. You may want to look at one of the accelerometers with a +/-3G range, or consider a tilt sensor.

  • Would this be a good device to tell when something has stopped moving? IE the object like a bike or a car is moving and then it comes to a stop, would this be able to read that and be able to trigger an action.

  • Hi. I was wondering if I would I use this accelerometer to detect taps?

    • Kind of. This accelerometer just has analog output. Once you read the data into your microcontroller you can figure out what a tap looks like and program the board to recognize that. There are accelerometers that can calculate that for you but it would have to be a digital one.

Great ADX377 solution

The ADX377 is exactly what I needed for my latest project, however on ordering my first one, all I got was the IC in the middle.

Then I found Sparkfun’s breakout board. Now the part of my project that needed the uber-accelerometer is up and running perfectly!

Thanks guys!
