▶ Measurement Principle
The product utilizes a composite measurement with a static pressure sensor and a conductivity sensor to detect waterlogging. It senses waterlogging through changes in water pressure caused by the water level. In the absence of waterlogging, it reports safely every 6 hours (configurable). When waterlogging is present, it reports every 5 minutes (configurable).

Application Scenarios
Measurement and early warning of waterlogging in municipal roads, park roads, and important facilities (such as transformers and other electrical facilities, power stations, substation, etc.).
Installation Location: Road curbs, side-hole installation.
Important Note: When using NB-IOT for direct wireless upload, always confirm the NB signal strength and stability at the installation point, as this may affect the reliability of data transmission. If the quality of the NB signal cannot be confirmed, please opt for the more stable LoRa RF model. The default choice for the NB model at factory is: Telecom Operators!
