Review: Outstanding customer support, nice sensor that does what it claims, works with older BT 4.1 devices - I had problems with the first unit I purchased. I followed the manual provided but I could not get it to work. Also, the software on the company website included source code examples for Windows but only the compiled apps for android, not source code examples. So I sent and email to the company contact, asking for source code examples for android. The reply was almost immediate, very helpful and polite, with a link to download the code samples. I then wrote again regarding the issues I was having with the device not connecting neither via USB nor BlueTooth. Again, the reply was immediate, and we went back and forth before reaching the conclusion that the device was defective (I was worried it was a compatibility issue with an old BlueTooth 4 device, but that was not the issue). I asked desertcart for a replacement which arrived promptly and is working perfectly. So overall, although I had some issues, the customer support was outstanding and solved all of them. As for the device, it does what it says it does, and well. As for the worries indicated in another review: I agree, the documentation could be better and more clear, but it is clear enough. As for the app not being on Google Play, I believe the app is an example, not a commercial application. This is a sensor to be used in custom solutions/applications, the software is just to show its capabilities. But it is not spyware not does it contain viruses (I have a very strong protection system with 3 different scanners and no one found anything). Actually, the code package downloaded from the company web site even includes firmware code and PCB layout, so actually it seems that rather than trying to steal the customer's intellectual property they are making their own available to their customers!
Review: Solid device but data export could use an upgrade - Got this for my daughter to use in a science experiment. It connected to both our Android phones and older cheap low-power model and a much higher end model. It did this very quickly and very easily. You need the app or to use PC software to actually visualize and record any information coming off the device unlike an older larger and much less capable accelerometer I used to have which would save text files in its on board memory. I believe this system is much better. We have not tried hooking it up to PC computers yet because that process looks much more involved in the app connection to phone to less than a minute. Recording and sharing the data stream from the phone is also pretty easy but it could use a little bit of improvement. Currently files are only available to be transferred off the phone by accessing them one at a time with the built-in file previewer and then hitting the share button and saving them out to a service like Google drive or OneDrive. This works but it would be better if there were a way to select the multiple saved files and export them all at once. Newer versions of Android do not allow the app to save these files in a commonly available folder such as downloads so using a file manager or plugging the phone into a computer via USB doesn't let you access the saved data files. In early testing the device appears to work perfectly well for the intended purpose.

## Questions & Answers

**Q: Dows WT901BLECL work with Arduino or Python, Raspberry Pi or other microcontroller? Or other program?**
A: WITMOTION does not offer support or sample code for integrating the WT901BLECL with other MCUs. Instead, compatibility with various systems or other program necessitates the development and coding efforts tailored to the sensor's protocol.

**Q: How to setup the sensor connection of WT901BLECL? If I get problem with it, what shall I do?**
A: WITMOTION uploaded several step-by-step videos for PC software, iPhone, and Android APP connection to the product description page. Send message to us directly. Tech team response time: 12H -- support (at) wit-motion (dot) com

**Q: Does this sensor have the timestamp?**
A: The WT901BLECL does not have the timestamp. You can search ASIN, B01N99BUMR for purchase.

**Q: Can it be a suitable sensor for measuring vibration? Can it measure the displacement?**
A: The WT901BLECL IMU sensor can measure and output 3-axis acceleration, angle raw data and it cannot measure the displacement. It will require a formula converting raw data to vibration data. Recommended vibration sensor: B0C6KBSCLH.

**Q: I am seeking for a sensor with higher angle accuracy, which one is better?**
A: The X, Y-axis angle accuracy of WT901BLECL is 0.02deg, if you need a higher level of accuracy, please find HWT905 sensor with 0.05deg accuracy, B07G21XRV6 for purchase.

### ⭐ Good for some hobby projects
*by W***R on November 1, 2025*

## Technical Details - Product: WT901BLECL MPU9250 - Interface: Bluetooth BLE - Issue: Gyroscope unit oscillation (rad/s ↔ deg/s) - Reproducible: Yes, every session shows oscillations - Firmware: [check your version] - Tested on: iOS 18.6.2, iPhone ## Recommendation **DO NOT BUY** if you need reliable data. Spend the extra $20-40 for: - MetaMotionR by mbientlab - Movesense sensor - Adafruit BNO085 For hobby projects where precision doesn't matter, this might work. For anything serious, the unit oscillation bug makes this sensor garbage.
