amazing. great value so fun

Short battery life and BT disconnects. Seller also charged a 25% restocking fee when I returned it.

Feels like it might have spyware when you download a sketchy app from a google drive. but I ran it in a VM and it seems to be harmless.

The first thing I noticed about the device is its size—it’s incredibly small, about the size of a thick postage stamp, and light enough that you could use it on a drone. It is small enough to almost swallow though very much not recommended. After connecting it to my phone, I was able to see real-time metrics on its axis and movement in real time. My parents have a house that is built on wooden piers near a river, and it’s designed to flex slightly with the wind. I’ve occasionally noticed that during the dryer’s spin cycle, if I pay close attention, I can feel the house wobble ever so slightly. This device would be perfect for measuring that kind of movement, and I also plan to leave it in place during a hurricane while we safely evacuate. The data it collects should be as fascinating as it is likely terrifying.For the occasional creative and esoteric use I think this device is perfect. No hurricanes yet down here in the south but there will likely be some soon.

What an amazing little device! I'm using it to measure involuntary leg movements at night (by taping it to my foot). It was a cinch to set up, and has worked perfectly so far. It's so small and light that I don't even notice it. I can imagine all sorts of potential applications in sports, beyond the industrial-type uses it was intended for. Highest recommendation to anyone interested in tracking and recording motion in 3d.

It only has TWO accelerometer axes. Too bad. And it did not connect well.

Don’t know if my unit is just hinky but this is the worst WIT IMU I’ve used yet.It will eventually connect but then it appears to update between 1 and 20 times per second

The sensor works great, USB-C to charge, lasts all day it seems. Connects via bluetooth and its simple. The software that comes with it (via google drive) is good. The company support is great. I had different needs on the scales in the graphing software and they updated the software and sent me a personal link with the update I needed. You can't beat that. The output can be several container types and I can import that sensor data to most other software no problem via CSV or txt, etc, and even Open Office reads it fine in SpreadSheets for custom graphing as needed (images included). Their custom software has great features (see my first image of all the real time data streaming in and graphing). I use this to measure acceleration changes to understand relationships of vibration and coupling as a form of tactile response with audio and transducers.

WT9011DCL Inclinometer• The instruction sheet that came in box is not useful. For example, they don’t even tell you how to turn the device on or off. It turns out that you push and hold the little button on the front, but you have to get your fingernail on it just right. There’s no good indication to tell you whether it’s on or off.• I could not find any documentation for the WT9011DCL on their web page. The best thing to do is go to the Amazon product web page and scroll down until you come to “Product guides and documents.” Click the top entry, “Instructions for Use,” which is a PDF file and is a much better resourceI first tried to get this running with my Samsung S23 Android phone. I downloaded the WitMotion app from the Play Store and installed it without issue. The instructions for pairing are clear. There is an extremely dim and easy to miss blue LED that flashes when it’s paired.• According to the instructions, your first step is to calibrate the sensor. Unfortunately, there is no Calibration menu on the Android App. This must be for the PC version?• The manual says the Bluetooth range when using a Samsung phone is: “Best Distance BD” = 56 m and “Max Distance MD” = 108 m. (BD and MD are not defined). To test this, my wife held the sensor in the kitchen while I walked outside away from her while watching the app on my phone. After only about 60 ft (~20 m) the display stopped updating. (This is basically a line-of-sight path with only the kitchen window in the way). When I walked back to the kitchen the display remained frozen. The only way I could get it working again was to disconnect and reconnect Bluetooth. I’ve tried several variations of the test and all with the same result. I’m disappointed that the screen kept locking up and I’m quite disappointed about the limited range.• The engineering on this seems to be quite good. The app lets me monitor “Acc,” which graphs x, y, and z tilt angles. There is “Gyro,” which graphs x, y, and z angular acceleration, e.g., it senses when you turn the sensor in any direction. My favorite is “Angle,” which is like a bubble level showing the N-E-W-S sensor direction along with a graphical bubble showing tilt in x and y directions. Finally, there’s “MagField” showing the x, y, and z magnetic field values. The best thing is that the values are smooth and non-noisy, presumably a result of using Kalman filters.PC application.• The manual gives a link for software download, but it’s a Google drive with a bunch of strangely labeled directories and files. I was not able to successfully follow their directions to download the software.• Fortunately, their video tutorial is somewhat more useful.• My old PC doesn’t have built-in Bluetooth, so I needed to use the provided Bluetooth USB plug. Unfortunately, I haven’t been able to get my PC to recognize it. I tried an old Bluetooth adapter from my junk box, which my computer recognizes as a Bluetooth device, but sadly, the MitMotion software doesn’t see it, and won’t connect to the sensor.• I’m stuck and tired of messing with this. I’ll eventually try to contact customer support for help, but right now my out-of-box experience is not good.Bottom line: The engineering on this sensor seems top notch. If I can ever get it working, I think I’ll like it (except for the disappointing Bluetooth range). The documentation is poor. My advice is to spend some time looking at the documentation before you buy this and make sure you know what you’re getting yourself in for.Edit: On a positive note, I was contacted by their customer support and offered a full refund. I'll still try to get this thing working when I get some time, but in the meantime, I'm impressed that they stand behind their product.
