  • Works well with easy software
This is a great little tool that works as advertised. The blue tooth phone app works great, so good I haven’t bothered to use the Bluetooth thumb drive sold separately. It can be zeroed for how it is placed and then monitored. The software is good. I ziptied the module to a high strength magnet which allowed me to move it easily to different location for use as a vibration monitor not exactly what it was meant for but it works well. ... show more

  • Decent little product that does NOT work
The media could not be loaded. I have a few of these and they do a decent job, but there are major issues with the apps. I can no longer get them to work on my iPad or my Android phone. On my iPad I can connect and record data, but it crashes when I try to access the data to transfer it to my computer. On my Android phone the app never quite gets fully open before crashing. Other than not being able to get the data anymore here are the positives: these do in fact record at pretty decent frequency (100 Hz - 200Hz depending on the model... I have a few). However, don't plan on doing an FFT of the data. The sampling rate varies, and the timestamps aren't logged with enough accuracy (or even precision) and as such it injects a lot of noise into an FFT. ... show more

  • Works great. Just what I was hoping for.
Works great. I was hoping the sensitivity would be good, and it’s actually better than expected.

  • Ignore the One Star Reviews... this thing is awesome for the price. Battery Not Included
So it is a bit of a pain in the butt... stuff to complain about: 1. Make the cable so that you can transmit via USB... it is 2 whole wires. I would gladly pay $2 extra dollars for the extra wires. 2. Make sure that your solder connections between the bluetooth board and the actual gyro board are good... mine needed a bump 3. For pity sake, get someone that actually speaks English to write your manual and include the documentation for the bluetooth and where the led light are located... That being said... 1. Once I took it apart and got the blue light to come on for the bluetooth, Windows 10 found it flawlessly. Found it even after I removed power and replugged it back in. 2. Adding a $1 AA battery pack to the gyro makes it cable free which is most excellent. The AA pack that holds 3 battery powers the gyro beautifully. 3. The software is excellent except for the fact that once you start the record, there isn't a STOP button anywhere to be found... it ran all night and saved the data... oh my! To all the people that gave this a 1 star due to the fact that you cannot ship via air with a battery installed, get a battery pack and solder it into place. I managed... took all of 3 seconds. So the part numbers that you need for research: BWT901CL - which is what you purchased which includes: HC-06 - this is the part number for the bluetooth module. If you ask google for the data sheet, it will find it. JY901 - this is the actual gyro board The switch on the side does nothing... when the unit is plugged into USB power there should be a red light and a blue light above the switch. If the blue never lights off, the solder on pins 12 and 13 need a touch up... you need a very small (tiny) solder tip on your iron to fix it. The software is on the wit-motion.com web site. You will need chrome and the google translate to read it and find the downloads... you need the software for the JY901... and not for the actual part number. I hope that this helps everyone who purchases one of these. Get over the battery problem guys... this girl that has used gyros for aerospace that cost thousands of dollar and are not bluetooth, this one is excellent for the application that we are using it for, gets rid of a ton of cabling and comes with its own data collection software with software source samples. Have a wonderful day! ... show more

  • Works well, good price
It worked with the test software of Witmotion on first try, great attention from Kyle from support team, unfortunatly I am not experienced enough to link the device to a head tracker software, which was my first purpose, but nothing to do with the quality nor performance of the device, only my lack of knowledge. I would recommend WitMotion products , great price and awesome customers' support. ... show more

  • Does not work as a native sensor when added to Android OS
I bought this sensor because my tablet lacked sensors needed for an application I wanted to run. I followed the instructions. Downloaded the latest app off their Google Docs site for this particular sensor and then connected to the device via bluetooth. The app and sensor paired flawlessly. So, then I downloaded a couple apps (Sensor Tool and Sensor Toolbox) so I could get the details on the current installed and provisioned sensors. The sensor components did not show up at all for this device. So, then I plugged it in using the TTL (USB) connection. Again, the WitMotion app saw the sensor and I was getting input from it. However, the native app I wanted to use didn't see it and the sensor apps I installed didn't see it either. Bummer. I was hoping to find a way to quickly add functionality to my Android Device but apparently this isn't the way. Maybe a virtual driver or some soft of translation layer could be written? But I am not a developer and I wasn't able to find anything from the GitHub or the GDocs drive they pointed me too. I really wish they replied to my email enquires about this before I wasted resources getting it and testing it and then sending it back. Probably will end up in a landfill somewhere.... What a waste. ... show more

  • Could be good if it connected.
It didn't connect, so I wouldn't know if it was good or bad. I couldn't get help to get it to connect either.

  • Works great!
Quite a remarkable device. I used it to measure the vibrational motions of a camera mount in church. Setup & software was difficult, but with help from Kyle in China, I got it working.
