Product Overview

The HK19 is a low power consumption IoT device that is typically used to monitor sewage or water supply manhole cover status in real-time. Once it’s installed onto manhole cover, real-time alarms can be transmitted to cellphone APP or remote software platform in the event that the cover gets opened or immerged into water.

Real-time monitoring for sewage manhole cover is especially important. Because of the nature of wastewater, there are different types of toxic gases in the manholes. In the event that the manhole cover gets lost, it’s extremely dangerous if a person drops into the manhole.

The HK19 smart cover not only empowers water utilities to identify abnormal conditions for manhole covers, but also greatly improves asset management for all the manholes as the cellphone APP or software platform shows complete list of manholes as well as accurate location for each manhole on the map.

The black antenna goes outside of the product on the back side, which gives it good protection after the product is mounted. This position of the antenna is actually the best position for placing antenna, that ensures best signal sensitivity.
