A covered enclosure surface sensing device, with an on-chip 2-D phased array radar sensor, beam-steering to create a three-dimensional image of the enclosure's interior. An environmental encasing contains a processor, a motion detector, a communication module coupled to an external communication antenna, a power source. It is attachable to a lid or upper side surface of the enclosure. After scanning, the device measures positions of, if present, flexible surfaces and obstructions within the enclosure and a level of liquid or powder in the bottom of the enclosure. If the enclosure contains an open channeled inlet and outlet, it measures liquid levels in the inlet and outlet, the position of the inlet and outlet, and the speed of fluid in the inlet and outlet. If the motion detector detects a threshold movement of the lid or surface sensing device, the phased array radar sensor performs a reorientation scan.

Phased array radar for fluid sensing

An environmental sensor device with a sensor enclosure is configured for use in a gas environment. An enclosure support, at least one sensor on a face of the enclosure; and at least one debris sloughing structure is used. The debris sloughing structure is composed of a channel with a set of inner and outer ridges disposed in the enclosure around a periphery of the at least one sensor, wherein a top portion of the debris sloughing structure above the at least one sensor and lateral portions of the debris sloughing structure on lateral sides of the at least one sensor. A shape and arrangement of the debris sloughing structure carries condensate or contaminants forming on non-sensor areas of the enclosure away from the sensor and to a bottom portion of the enclosure.

Sensor housing with debris sloughing structure

A combined sewer/enclosure overflow (CSO) sensor system is described for accurate detection and measurement of overflow events. From the combined data, trending information can determine if there is debris accumulation. Rain masks can be used in the trending data to measure overall health. External sensors in combination with the CSO sensors provide predictive information and additional levels of information/data accuracy. The sensor system automatically and remotely monitors CSO locations and provides real-time data regarding start times, stop times, duration, and flow volumes of overflows that occur in these structures and provide regulatory and public notification of these events.
