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

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.

Fits the purpose for the price.

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?

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.

Low sampling frequency. Not useful for serious projects

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.

This is good

It would be nice if the menus were in ENGLISH!

excelent produit au meilleur prix. le reste sont le double du prix. par contre je me debrouille bien en ordi et la prise en main se servir du logiciel et tout peu etre ardu pour quelqu'un qui connait pas ca. mais il y a aucun produit qui fait se quil fait a se prix.

funktioniert einwandfrei, Echtzeitmessungen werden problemlos auf dem Smartphone dargestellt (Android)

Piccolo e funzionale. Ho usato solo l’app per smartphone che è ben fatta ma, volendo c’è anche un programma (immagino ben più completo) per computer.

Es preciso, portátil, no ocupa mucho espacio. Solo verifique qué esté tomando lectura cuando graban, 1 de 10 veces no ha grabado, solo apagar y conectar de nuevo por Bluetooth. Pero en general gran dispositivo.

Verbindung zum Handy via App mangelhaft und deshalb nicht einsetzbar
