Manhole Cover Sensors

Manhole cover sensors The Best Sensing Solutions—Directly from the street Manhole Protector: From Manhole lock to Manhole cover open detector Manholes leading to underground supply systems are essential for their maintenance, for example, it concerns telecommunication networks, water supply networks, gas supply networks and electricity networks, and so on. Although it is very crucial to a city’s operations, the manhole can be one of the least protected and most vulnerable assets. Nowadays manhole cover failure such as metal theft (for manhole cover or copper cable underneath it) is on the...

Manhole cover sensors support two optional wireless communication methods -- UNB (Ultra Narrow Band) IoT technology and NB (Narrow Band) IoT technology. Both technologies have transmission ranges of up to several kilometers in urban environments, with very low power consumption, data are then transmitted to cloud sever for further processing and delivery into the end-users system.
