Kindest regards, Kyle Witmotion Team **Q: do these have reverse voltage protection?** A: Hello, Our sensors have directional voltage protection. As long as the voltage is not the maximum and the reverse connection time is not long, there will be no problem. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Witmotion support *by M***Z on August 6, 2020* “The sensor works as expected. At the beginning there were some issues for get the sensor works. I contacted the Witmotion support and they solve the problem. Good sensor performance and excellent technical support!” ### ⭐⭐⭐ Conflicts *by M***B on March 20, 2024* Caused the computer to hang up and freeze but the seller helped ### ⭐ Do not buy for Python or Raspberry Pi *by R***E on February 9, 2023* Witmotion's website says there are no python software examples for this device. That is different than what you would think by looking at the ad on Amazon. The sample "python" software (they provide in a large zipped file that you download from their website) is actually in C++. I have spent four solid days trying to find a software example on the internet that I could get to work, but there is always something wrong or missing that keeps this thing from working. Oh, and the one "good" software example I found was written in a class structure, and I don't understand how the class structure works, nor was I able to unravel what it was trying to do to write non-class structure software. It also wanted to import "typing", and I think "typing" may be obsolete(?). VERY FRUSTRAITING. I am returning this to amazon. Also, it must be connected to the USB port. You can not connect it to the header pins. ## Frequently Bought Together - 【WT901C-232 9-Axis Vibration Inclinometer】High-Stability Acceleration+Gyro+Angle (XY 0.05° Accuracy)+Digital Compass, Triaxial MPU9250 Gyroscope Sensor【Kalman Filtering】for Arduino, Raspberry Pi - Sparco (50001) Bottom Mount Seat Hardware --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/174759036-wt901c-232-9-axis-vibration-inclinometer-high-stability-acceleration-gyro](https://www.desertcart.pl/products/174759036-wt901c-232-9-axis-vibration-inclinometer-high-stability-acceleration-gyro) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-06*
