Integrates multi-type sensors (customizable for water level, displacement, tilt, etc.), supports NB-IoT/LoRa remote communication, and can upload manhole cover status data in real time;
Automatic alarms for abnormal status (e.g., manhole cover displacement, excessive water accumulation in the well) help improve the response efficiency of pipe network operation.
SMC composite material has good resistance to humid/mild corrosion environments, with an expected service life of over 20 years under proper use;
Non-metallic material has no recycling value, which can alleviate the theft issue of traditional smart cast-iron manhole covers to some extent.
Supports customization of sensor types, communication methods, and logo styles, which can match the management needs of different smart scenarios;
The lightweight composite material (about 25kg, vs. ~45kg for the same-sized smart cast-iron cover) can be installed/maintained by one person with tools.
The intelligent module is equipped with a long-life battery, with a battery life of 3-5 years (depending on usage scenarios);
The anti-slip surface + sensor protection design requires only surface and sensor probe cleaning for daily maintenance, with relatively low cost.

Clean debris from the inspection well opening, fix the support frame and debug the intelligent module communication signal;
Align the cover with the support frame, lay it smoothly and fasten the buckles, and confirm the module power supply is normal;
Verify the monitoring data in the background and complete the intelligent function initialization.
Clean the cover surface and sensor probes monthly to avoid blocking affecting monitoring accuracy;
Check the intelligent module battery level (remotely viewed in the background) every six months, and replace it if necessary;
If damage or module failure occurs, send an email to jschangan111@gmail.com to contact the manufacturer for handling.
With over 10 years of composite manhole cover production + 3 years of IoT module integration experience, its smart manhole covers have passed relevant certifications for municipal smart facilities;
Supports full-link customization of sensor types, communication methods, and logos to meet the needs of different smart scenarios;
Bulk orders include intelligent module debugging + background docking guidance services.
