蒙自DG-SMC-S-I Smart Manhole Cover
Product Description
Measurement principle
Smart manhole covers, which enable monitoring and early warning of underground equipment and cover conditions, are an indispensable component of various smart utility‑network management systems. They address challenges such as the humid, flood‑prone underground monitoring environment, limited power supply, and poor communication connectivity, making them suitable for installation in manholes along urban arterial roads, residential neighborhoods, sidewalks, non‑motorized vehicle lanes, parking lots, and other areas.
