Overview
A smart manhole cover terminal combining tilt and overflow sensing with NB-IoT communication to a cloud platform. It reports abnormal opening and closing, low battery and removal, raises alarms in real time and supports work-order dispatch, for municipal, water, gas, power and telecom underground networks.
Features
- Status monitoring: normal / abnormal / low battery / removal / open; tilt threshold 26° by default, adjustable 2~179°, accuracy ±1°.
- Overflow detection: capacitive sensing triggers a full-overflow alarm when water covers the housing.
- Alarm handling: map highlighting, SMS / email notice, work orders and on-site photo upload.
- Low power: ≤20 µA standby, 4000 mAh lithium battery, five-year life depending on reporting frequency.
