24/7
Continuous measurement, no manual patrols
Stop work early before flooding, no manual watch needed
Water-level sensors installed in rivers or open channels measure 24/7, with graded alerts sent instantly to site representatives and safety officers. Trends can return to customer systems via API.

At a glance
SenseOS river level monitoring installs water-level sensors in rivers or open channels to measure water levels 24/7. When levels reach a graded alert threshold, the platform instantly notifies site representatives and safety officers, so work can stop before flooding without anyone watching the water manually. Units run on solar or battery power, need no mains supply or foundation, and are usually installed within half a day.

How it works
When water reaches each sensor, the matching alert level is triggered.

NB-IoT moduleReadings are sent to SenseOS over the NB-IoT network
Workflow
01Wireless and battery-powered, typically done in half a day
02Sensors report on schedule and send data over NB-IoT
03Data is evaluated 24/7 against preset risk formulas
04SMS, voice call, email and WhatsApp alerts to the right people
Web and mobile views show water levels, alert history and pump status. Data can return to customer systems through API, while more monitoring applications can be added later.
