Walabot DIY in hands on: RF sensor detects pipes, breathing and movement

Monday, September 4th, 2017 | Gadgets

The Israeli company Vayyar has presented its sensor Walabot DIY at Ifa 2017. The device can detect high-frequency RF waves behind pipes and lines, thus preventing accidents. The sensor can also do much more, as Vayyar showed us in a detailed demonstration.

The functional principle corresponds to that of a radar: Walabot transmits radioswaves and receives their reflections. The changes in the signal are analyzed by an algorithm, depending on the application and the corresponding API, the signals are then filtered and interpreted.

The basic device is the 100 Euro expensive device to give users the possibility to safely drill in walls. The Walabot DIY is connected via USB to a smartphone, whose display then serves as a live monitor. Walabot DIY can detect cables and pipes at a depth of ten centimeters in concrete and rigging walls.
Walabot recognizes pipes, pipes and beams
After a calibration we can simply pull the sensor over the wall. The display of the smartphone shows us cables, tubes and bars. The depth of the obstacle as well as the material from which it is made are also shown to us – Walabot DIY recognizes metal and wood. The scan is extremely precise and reliable.
In the basic setting, Walabot DIY does not record the scans, but only outputs a live image. The new panorama function allows users to capture the scan results in one image. In this way, an entire wall can be scanned, after which the user knows exactly where obstacles are located.

Sensor technology allows further exciting applications
The technology of the Walabot DIY is also suitable for further applications, which we find even more exciting. With one of the three available development versions, which are available from EUR 150 upwards, radiowave technology can also be used to capture movements.
For example, a corresponding sensor can be suspended in a room corner; a sensor measuring approximately 30 x 30 cm can then detect movements in a field of view of 120 degrees and a range of 15 meters. A camera image is not recorded, which is why the technique Vayyar can also be used well in security-sensitive areas.
