A method for managing air quality may include, at one or more processors, receiving sensor data comprising a plurality of air quality parameters for an environment, wherein the sensor data is generated by one or more environment quality monitoring devices located in the environment, predicting an adverse air quality event based on the sensor data, and automatically controlling one or more devices to mitigate the adverse air quality event. An environment quality monitoring device may include a housing, a plurality of sensors in the housing and configured to generate sensor data comprising a plurality of environment quality parameters, a network communication device configured to communicate the sensor data over a network, and an alert configured to indicate an environment quality score of the ambient environment, where the environment quality score is based on at least a portion of the sensor data.

The present invention relates to a method for detecting an analyte, which is based on the detection of a signal caused by a change of the mechanical properties of a permeable freestanding nanoparticle composite. The present invention also relates to a method for determining the concentration of and/or recognizing an analyte.

Apparatus and associated methods relate to height-differentiated gas detection sensors attached to one or more tethers suspended from an unmanned air vehicle (UAV) platform. In an illustrative example, each of the gas sensors, for example, may communicate gas detection signal information to a signal processing module onboard the UAV platform. Each of the tethers, for example, may provide a data channel from the sensor to the signal processing module. Some tethers, for example, may supply operating power to one or more of the gas detection sensors. The UAV platform may advantageously deploy one or more low-cost, disposable, tethered gas detection sensors into vertically confined spaces (e.g., chimneys, vents), or along a length of pipeline, for example. The sensors may be deployed at a minimum predetermined height providing separation from the UAV to attenuate prop-wash with respect to the sensors.

A technique for monitoring and collecting environmental data is provided that supports acquisition and analysis of quality measurements of pollutants by sensors based on different technologies in an integrated manner. The system includes a primary substrate having a plurality of sensor modules, each sensor module configured to couple to a sensor, and a manifold having a plurality of flow hoods, each flow hood disposed on a top surface of a sensor and connected to another flow hood or component in the manifold. In some cases, the sensor modules are gas sensor modules, and the sensor is a gas sensor. The manifold thus provides a closed system through which a fluid sample can flow across a series of gas sensors in an actively controlled manner that enables independent flow control over each individual gas sensor while limiting exposure of the fluid sample to potential sources of contamination.

Disclosed is an air-quality detection apparatus including a casing body including a bottom and a side wall, a first printed circuit board (PCB) disposed horizontally above the bottom, a second PCB disposed horizontally in a first region above the first PCB, a CO.sub.2 sensor mounted on the second PCB, a volatile organic compound (VOC) sensor mounted in a second region on the first PCB that is closer to the side wall than the first region, a third PCB, which is disposed horizontally at a position spaced further upwards apart from the bottom than the first PCB and at least a portion of which is disposed in a third region that does not overlap the first PCB when the bottom is viewed from above, a fourth PCB disposed horizontally above the second PCB and the third PCB, and a dust sensor mounted on the fourth PCB.

The systems of the present invention provide monitoring and recording means for monitoring and maintaining a history of one or more parameters associated with a building or a particular location. The system can be preset with default actions to be conducted as a result of certain events or changes in certain parameters being detected. For example, the water and/or gas utilities can be programmed to shut down if smoke is detected, indicating the possible presence of a fire, or if the temperature drops below freezing temperature. All utilities, including gas, and water can be programmed to shut down in the event that a potentially significant change in a monitored parameter is detected.

A multi-core sensor system in taxi roof light is provided. The multi-core sensor system can intelligently determine whether the change is caused by the sub-sensor failure or sudden pollution, when the data detected by the sub-sensor suddenly changes dramatically, so as to increase the reliability of detection data of the sub-sensor. The multi-core sensor system can automatically determine whether the repair is needed when a device fault occurs, thereby ensuring the continuity of the sub-sensor detection data; which has significant value for continuous monitoring required for a haze treatment operation. In addition, human and material resources for device maintenance may be saved, thereby reducing waste.

Embodiments of a gas detector with a first gas sensor having a first gas specificity and a first response time and a second gas sensor having a second gas specificity and a second response time. The first gas specificity is different than the second gas specificity, the first response time is different than the second response time, or both the first gas specificity and the first response time are different than the second gas specificity and the second response time. A readout and analysis circuit is coupled to the first and second gas sensors to read and analyze data from the first and second gas sensors, and a control circuit is coupled to the readout and analysis circuit and to the first and second gas sensors to execute logic that operates the first gas sensor, the second gas sensor, or both the first and second gas sensors.
