Description: The ADXL337 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned analog voltage outputs that measures acceleration with a full-scale range of ±3g. 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, disk drive protection, game controllers, and image stabilization.
Getting the ADXL337 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.
Based on 1 ratings:
I used this in a tilt-based toy and it was very easy to interface with. Very approachable, not as intimidating as an accelerometer might seem.
From the datasheet you can easily calibrate it to get decently accurate G values. From there I got angle data and used it for my project.
Cheap and effective. A little vulnerable to vibration so be sure to take an average of a few readings.
