Description :

TheManhole Opening Detector uses the NB-IoT network to transmit messages and is designed to remotely control unauthorized access to wells. The sensor allows you to track the opening of the manhole and prevent emergencies.

The sensor is mounted under the manhole cover and is triggered when the cover is lifted by a signal from two manhole position sensors. The sensor antenna is displayed on the outside of the manhole, which ensures reliable radio reception over a long distance.

The sensor is installed in a metal case, which is attached to the manhole with bolts and additional welding by electric arc welding.

The sensor board is additionally protected by a sealed plastic case, which is equipped with a tamper sensor. In addition, it is possible to connect various devices for recording the state of wells: a flood sensor, a temperature sensor, a humidity sensor, etc.
