Digital water level sensor

Online water level readings

Knowledge of the water levels in creeks, streams, storm water reservoirs and more, can be valuable in many situations. This price friendly sensor provides an opportunity to read the water levels. The points can provide an efficient effort with weed cutting and maintenance and inform the local people of water levels to prevent damage, or information to those who are interested for other reasons, like fishing. You monitor the data on this site or through an API integration on your own devices.

The system is already fully functioning in several municipalities around the country. Please do not hesitate to contact us, if you are interested in the system.

The sensor makes a reading every 15th minute, which registers in the system. The reading is done by a pressure sensor, where the system calculates the water levels based on the pressure load. The water levels can be read as water level or depth.


The sensor is transmitting data through the Sigfox network, which cover 99.7% of Denmark. Sigfox is a cloud-based low energy network, which make local configurations like Wi-Fi or SIM-card irrelevant. Sigfox is a very secure system for data transmission and -storage.

Instruction with purchase

It can be necessary to install a repeater in areas not completely covered by the Sigfox network, to avoid interruptions in the data transmission. You purchase the repeater by contacting the customer support on this site. You can also annul the deal, if you are not interested in purchasing the repeater. In that case, the customer is responsible for freight charges revolved in the return, while any start-up fee and subscription are refunded.

Freight charges always fall to the customer and can be viewed in the web shop.

You can buy a new unit for 333,33 EUR incl. installation, if the unit is vandalized, or damaged from causes that fall outside HedeDanmark’s liability. You also purchase a new unit without installation at 200 EUR + freight. The customer continues with the same subscription as before in both scenarios. The product must be delivered in a functioning condition within 5 business days, if the subscription is terminated. The customer will be charged DKK 1500, if they fail to do so.
