Polysense Announces Smart City Manhole Solution: Multi-Parameter Monitoring, Flexible Wireless Connectivity and IP68 Enclosure

Manholes of all kinds, including electricity, water and gas, and communications, are everywhere in the landscape of every city, as a critical part of the city infrastructure. Proper maintenance and monitoring of such is increasingly on the agenda for any city government to ensure the smooth operation of the city infrastructure.

Manhole covers can be illegally opened or tampered with; manhole flooding can occur due to inadequate drainage system; critical asset in the manhole can be damaged; and a dangerous environment can build up in the manhole.

The Polysense smart city manhole solution supports the following:

1. Choice of wireless uplinks: LoRaWAN, NB-IoT, or Wi-Fi (LTE to be available in Q4 2019) 
2. WxS8800-021CM (LoRa)/WxS9810-021CM (NB-IoT)/WxS7800-021CM (Wi-Fi) 
3. Dimension: 355mm x 80mm x 80mm (including antenna length) 
4. Wide range of use cases: illegal opening and tampering of the manhole cover; micro-environment (temperature, humidity, light, pressure) inside the manhole; water level and presence of dangerous gases in the manhole; asset protection in the manhole 
5. IP68 enclosure customer designed for harsh manhole environment and efficient installation
6. Battery operation of 5 to 10 years

Manhole status is monitored in real time. Once an event is detected and reported, an alert is sent to the IoT cloud platform for visual display, to smart phone app or via email or text message, so immediate attention is given.
