Once upon a time, in the picturesque landscapes of Sweden, an engineering consulting group faced a formidable challenge: how to effectively monitor and manage groundwater levels in a way that harmonized with the environment and met the needs of burgeoning infrastructure. As the demand for sustainable water management grew, a beacon of hope emerged in the form of ELLENEX IoT sensors.


Our story begins with a dedicated team of engineers determined to revolutionize groundwater monitoring. They embarked on a quest to find a solution that would overcome the hurdles they faced - spatial variability, data accuracy, power efficiency, and network connectivity.


The team's journey led them to ELLENEX, a renowned Industrial IoT device manufacturer. ELLENEX introduced them to the PLS2-L, PLD2-L, PLC2-L, and PLM2-L sensors, LoRaWAN-enabled sensors to meet different requirements of the end user head. Intrigued, the engineers knew they had found the answer they were seeking.


The first benefit of the LoRaWAN level sensors was a revelation. The low-power design meant extended battery life, and the engineers marveled at the thought of up to 80% fewer maintenance visits. This reduction in operational costs would save time, resources, and money - a boon for their mission.


Excitedly, the engineers discovered that the LoRaWAN level sensors transmitted near real-time data automatically through LoRaWAN networks. The days of laboriously collecting data were over, replaced with seamless automation. Their workload lightened, and the team could now focus on other crucial aspects of their groundwater monitoring tasks.


As the team integrated the LoRaWAN level sensors into their groundwater monitoring network, they discovered the true magic - scalability and versatility. The sensors could effortlessly monitor groundwater levels across multiple locations simultaneously, creating a comprehensive network of data. The engineers were impressed, for they could now embrace new monitoring sites without the burden of extensive modifications.


With near real-time data insights at their fingertips, the engineering consulting team made informed decisions like never before. Fluctuating groundwater levels were promptly identified, enabling proactive responses to changing conditions. Risks were mitigated, and potential damages minimized, all thanks to the PLM2-L sensors' near-instantaneous data updates.

Implementing IoT solutions like PLM2-L, results in up to 80% reduction in maintenance visits, leading to significant cost savings in labour and operational expenses.

In the midst of their success, the engineers encountered another pleasant surprise - data reliability. The sensors boasted impressive data transmission reliability, ensuring critical groundwater information was consistently accessible. The downtime was drastically reduced, allowing the team to concentrate on data analysis and further improve of their efficiency.

  • Cost Savings: The IoT sensors resulted in up to 80% reduction in maintenance visits, leading to significant cost savings in labour and operational expenses.

  • Real-time Data Transmission: ELLENEX sensors achieved near-instantaneous data updates through LoRaWAN networks, eliminating the need for manual data collection and reducing data lag.

  • Scalability and Versatility: Sensors seamlessly monitored groundwater levels across multiple locations, showcasing a scalable and versatile solution for expanding monitoring networks.

  • Data Reliability: Sensors boasted an impressive 99.5% data transmission reliability, ensuring uninterrupted access to crucial groundwater information.



With streamlined maintenance operations, minimal disruptions, and optimized labour, the engineering consulting group found itself at the forefront of sustainable groundwater management. The LoRaWAN level sensors not only saved the day but paved the way for a greener future.


In their quest for sustainable groundwater management, ELLENEX IoT sensors had proven to be the hero our customers needed. With their power-efficient design, automated data transmission, and scalable versatility, the sensors empowered the engineers to protect the precious groundwater resources for generations to come. As the story of groundwater monitoring continued to unfold, ELLENEX sensors remained the champions of a greener and more environmentally conscious tomorrow.
