The myDatalogGauge records the current groundwater level. The gateway transmits the data to the UTK data portal via mobile radio. The map display provides an overview of all measuring points. As long as the dots are green, everything is fine. If a set level is exceeded, an alarm is sent to the administration via e-mail and SMS. The battery operation of the myDatalogGauge level measuring stations and the very long runtime of up to 10 years are the major advantages of the system.
