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

Works as expected with an impressive price. Excellent buy

This is a handy little sensor and vibration meter. You could use it to measure earthquakes as well I suppose. It does temperature as well. I’m happy with it. Helped to meet to verify that the sky trumpet rumblings were not in fact earthquakes. It also helped me to verify that the refrigerator was indeed getting to the proper temperature.

I bought the WTVB01-BT50 model, which I thought would include a vibration (velocity) meter in my product. This module can measure vibration (Velocity and displacement) RMS in mm/s. However, the resolution of the velocity in mm/sec is an integer value of 1 mm/sec. It does not allow to obtain decimals, which is not very convenient when the readings want to compare with the ISO 10816 standard. To be professional equipment, the velocity measurement must be read with at least one decimal resolution, and two decimal places would be very convenient. Could you improve the product by including in the speed at least one decimal resolution example in the range of 0.0 to 49.9 mm/sec or better, 0.00 – 49.99 mm/sec?

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.

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.

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.

Fits the purpose for the price.

This is good
