Due to the lack of infrastructure, it was sometimes necessary to drill up to 40 metres through the rock into the chambers. Microtronics comes into play when it comes to data transmission. On the surface, there are devices of the type rapidM2M C3 andmyDatalogEASY IoTmini with a solar panel for self-sufficient operation. These send the data via GSM to the central web interface.
The data can be viewed by the engineering office and the authorities via the online platform and the FTP report. When the groundwater level falls below a threshold value, an alarm is automatically generated.
