Your cart is empty.Features: The device offers a variety of special detection features. Active and Inactive Detection Detects the presence or absence of motion by comparing the acceleration on any axis with a user-set threshold. Percussion detection function can detect any direction of single vibration and double vibration action. Free fall detection function can detect whether the device is falling. These functions can be independently mapped to one of two interrupt output pins. The patented integrated memory management system uses a 32-level first-in-first-out (FIFO) buffer to store data, minimizing host processor load and reducing overall system power consumption. Specification: Main chip: ADXL345. Model: GY-291 Power supply :3-5v. Means of communication: the iic / spi communication protocol. Measuring range: ±2g /±16g

I bought these to measure resonance levels from vibrations in a 3D printer (a feature in Klipper firmware). Hooked these up to a Raspberry Pi and they worked fine.Basically, the firmware vibrates the parts back and forth at various frequencies and using this accelerometer it can determine which frequencies move the most (resonant frequencies). It can then compensate for this and remove "ringing patterns" caused by resonance.The whole process worked fine using these accelerometers.Great price for these as well.

Worked easily and as expected for Klipper auto resonance tuning. 3 printers done for cheap when compared to cost of 1 board from Adafruit costing around 20$ each or Sparkfun

Used this product for variety of projects and experiments. In one project, I used it as a level sensor to build a balance beam with an Arduino Nano and DC motors with small fan blades. I noticed that the motor speed seemed to cause the Y-axis readings to vary dramatically, increasing the variability proportional to motor speed. Other than that, it is an inexpensive and useful sensor for many of my projects.

Went through 6 boards just for 2 that worked. Fortunately I only needed 2, so I just took the loss on the one failed board after the first return. The 2 functioning boards seem to work fine.

These worked great to test acceleration on some of my 3d printers and cnc laser

I use these for input shaper tuning with Klipper on my Ender 3 V2. They work great, no complaints.

Got these for my Ender 6 to calibrate Klipper. I only needed one, but I guess I have spares now.

The product looks great , quick shipping , I cant wait to try the for a vibration analyst project . Only recieved 3 of the 5 sensors quoted in the ad. Oh well I didn't need more than the three for now .

Product description says 5 pieces and the picture shows 5 boards and 5 pin headers. But I only received 3 boards and 3 pin headers.Misleading advertising.
