Remote sensing device

A remote sensing device for monitoring a condition within a water infrastructure network comprising:

• an antenna unit configured to be located at or towards a top surface of a water infrastructure component in the water infrastructure network, the antenna comprises a flat base for engaging with the top surface of the water infrastructure component, the antenna unit having an elongate connection shaft comprising a hollow depending therefrom, the elongate connection shaft providing a mounting structure on the underside of the water infrastructure component for receiving and supporting a structure;
• a monitoring unit for housing electrical components including a sensor for detecting a parameter, the monitoring unit removably mounted to the antenna;
• wherein the monitoring unit comprises a hub for mounting the monitoring unit to the elongate connection shaft, the hub being a region of the monitoring unit surrounding an opening of the monitoring unit, the opening configured such that the elongate connection shaft passes completely through the housing of the monitoring unit;
• wherein the electrical components are located in a cavity of the monitoring unit, arranged to be spaced radially around the hub and the monitoring unit is located in a region between the top and bottom ends of the elongate connection shaft;
• and
• wherein the antenna unit and monitoring unit are separate and individually water-tight structures.
