[BLE Vibration Sensor] WTVB01-BT50 Smart Vibration Module Ar-duino, 3-axis Vibration(Amplitude+Frequency+Displacement+Speed) Detector, Wireless Acceleration Shock Motor Monitor

Amazing device! very inexpensive for what it does and was able to predict a pump failure with it!!! Seems to work very well. I did modify this device with a magnet so that I could take it on customer sites and look for problems in their equipment. Very impressed with what it does. Long battery life and very durable. If I lose one, I won't be worried since it's not that expensive.

Work out as advertised

This is good

The app is currently very disappointing. The iOS version has multiple issues, and the Android version cannot replay recorded files (in my phone). The data display is not intuitive or useful. The Windows-based software has been flagged by antivirus programs, raising security concerns. Sensitivity for detecting ground vibrations is inadequate, and overall performance is glitchy. Playback functionality is also poor — you're forced to rewatch tests in real time, which is inefficient. In short, the software requires significant improvement across all platforms.

I like that this sensor is affordable and enables you to check equipment vibration to certain extent. Problem got complex when I tried to mount 6 sensors on a piece of machine to get the baseline information. Renaming the sensors was glitchy. I gave up after naming only two of them. I tried taking notes like e3:5e:84:36:57:5e was motor X, but that got cumbersome and made the data later hard to post process.The software is glitchy too. Playing back the data means you have to re-watch the test in real time. Software needs a lot of work.

Device has built-in battery. It charges via USB-C port. USB-C charging cable is included. There's also on/off switch and 2 LEDs: power and bluetooth status. Back cover is fastened with small Phillips screws, not glued to the case. This is great as I can later replace buil-in battery when it looses its capacity. Rotational angles, velocity, vibration frequency and displacement telemetry are streamed continuously from the device to connected smartphone. Ambient temperature, battery state and Bluetooth signal strength are also reported. Both Android and IOS are supported. Device is paired and bound via the app. You can bind multiple devices. App presents data in both tabular and graphical formats (scatter graphs). I am planning to use it with our new RC plane project that we are building with my son. Initially just to calibrate flaps, ailerons and rudder input limits and its central of mass distribution and bias if any (nose up or down during the flight). Later I want to figure out whether I can use WIT-Motion API to receive and process telemetry data outside of WIT-Motion Android app on my Ubuntu laptop for auxiliary remote real time feedback inputs into flight controls to enhance flight stability and correct navigation biases (persistent wind streams, ect). We also have Arduino based RC bot with ultrasonic radar sensor that may be controlled remotely by python script via Bluetooth connection. In addition we're planning to use it for in-house inertial navigation project with this bot.

Couldn't get the app to download. Extremely confusing. Returned

This along with the app lets you monitor and log vibration. I use it to detect imbalance in high-speed motor applications. Great for collecting data.
