Abstract
A monitor for monitoring the conditions of and around and under a manhole cover senses current conditions of the manhole cover and enables wireless self-reporting of such conditions at intervals and upon certain emergency situations arising. The monitor of the manhole cover includes a shell, a cover plate, and a base. The cover plate is detachably assembled with the shell. The base connects the shell with the manhole cover. The base includes a magnet to which the manhole cover is strongly attracted. The monitor is held to the manhole cover by the magnet. A mounting operation of the monitor is simple, requiring only placement by hand, and a mounting time is saved.
