With this portable Bluetooth IoT sensor - roughness tester, you can quickly and precisely measure the roughness of a wide variety of surfaces. To do this, the IoT sensor with Bluetooth is placed on the surface to be tested. With the positioning device, the roughness meter can be aligned on a wide variety of surfaces. A measurement with the IoT sensor can be carried out at the touch of a button. After the measurement has been carried out, the measured value is shown to the operator on the display of the IoT sensor. A progress diagram of the surface is also shown on the display.

When measuring the surface roughness, there are various measurement parameters that provide information about the roughness of the surface, for example the maximum roughness depth, the mean roughness depth and many other measurement parameters. After a measurement has been carried out, these can be displayed in the data memory of the Bluetooth IoT sensor.

After each measurement of the roughness, the recorded measured values ​​are saved in the IoT sensor with Bluetooth. Up to 20 measurement sequences can be saved with the IoT sensor. In order to process or analyze these further, the Bluetooth IoT sensor can be connected to a PC via the micro-USB interface and read out, analyzed and further processed using the free software in the download portal.

This IoT sensor has a Bluetooth interface. This Bluetooth interface can be used to establish a direct connection with an Android device. This has several advantages. The stored data can be displayed and analyzed directly on the Android device. The measured values ​​measured by the IoT sensor can also be exported and forwarded by the mobile device. In addition to transferring the measured values, it is also possible to control the Bluetooth IoT sensor via the connected mobile device. This means that the measurement parameters can be set directly on the IoT sensor. At the same time, a measurement process can be started with the Bluetooth IoT sensor via the Bluetooth interface. This has the particular advantage that, in contrast to starting via the buttons on a roughness meter, no vibrations are transmitted to the IoT sensor. As a result, the operator receives a more precise and at the same time more reliable measurement result from the Bluetooth IoT sensor.
