In various embodiments, an air quality-monitoring system (100) may include at least one sensor (106) configured to detect operation of a mechanism (110) within or at a boundary of an indoor environment. The mechanism may be external to an air purifier (102) associated with the indoor environment. The system may include a persistent memory (124) for storing data about the indoor environment observed by the at least one sensor (106). A controller (104) may be communicatively coupled with the at least one sensor and configured to: assemble the data into an air quality profile associated with that environment; determine, based on a signal from the at least one sensor and on the air quality profile, a likelihood that operation of the mechanism will cause a measure of air quality within the indoor environment to fail one or more air quality criteria; and selectively provide, based on the likelihood, an indication that operation of the mechanism will cause the measure of air quality within the indoor environment to fail the one or more air quality criteria.

An fluid monitoring system can include a filter having an upstream face and a downstream face and defining a form factor, a sensor package arranged within the form factor of the filter to detect at least one quality factor of a surrounding medium, a transmitter electronically coupled to the sensor package and including an antenna for autonomous wireless transmission of the detected fluid quality information, and a power subsystem coupled to the sensor package and the transmitter to provide access to continuous electrical power thereto.

A control system, comprising one or more smoke sensors, each configured to measure a level of smoke at a location within a building and to output a smoke level signal based at least in part upon the measured level of smoke. A controller configured to receive the smoke level signals and to control an operation of one or more energy recovery ventilation systems in a first mode of operation to recover energy when the smoke level signal is below a predetermined value and in a second mode of operation to evacuate smoke when the smoke level signal is above the predetermined value.

Smoke and/or soot damage to an interior of a property, such as a residential building or home, may be mitigated. A controller is in communication with a heating, ventilation, and air conditioning (HVAC) system of the property. The controller is configured to receive an alert and/or intelligent home telematics data generated based upon a potential presence of smoke in a location associated with the property, either exterior or interior to the property. In response to receiving the alert and/or intelligent home telematics data, the controller is further configured deactivate an air circulation function of the HVAC system to mitigate smoke or fire damage to the property. The intelligent home telematics data may be generated by various smoke, fire, audio, visual, infrared, motion, and/or other smart sensors mounted about the interior and/or exterior of the property.

A distributed security system includes a detection unit disposed at a first location. The detection unit includes a particle sensor that is configured to detect a particle count in first location. The detection unit also includes a housing enclosing a portion of the particle sensor. The security system also includes a camera disposed at a second location and having a field of vision encompassing the first location. The camera is configured to capture a video of the first location. The system also includes a server communicatively connected to the detection unit and the camera and configured to associate the particle count with the video.

The disclosure provides a system, method, and apparatus with features that allow hosts to be alerted of risks to the well-being of their space that may arise, for example, from a breach of contract, violation of local laws, or violation of established property rules. In one example an air analyzer is provided that includes: (1) multiple sensors including one or more of a digital multi-pixel gas sensor, a digital humidity and temperature sensor, or a particulate matter sensor, wherein each of the multiple sensors is configured to obtain a sample of air and derive therefrom an environmental attribute, wherein the environmental attributes provide a signature of the sampled air, and (2) a smoke classifier configured to classify a smoking event by comparing the signature of sampled air to signatures of a classification model.

An aerosol-generating system, and aerosol-generating device, and a charging case for an aerosol-generating device are provided. The system includes an aerosol-generating device; an ambient air quality sensor; and a controller. The device includes a housing having a chamber to receive an aerosol-forming substrate; and a heating assembly to heat the substrate when the substrate is received in the chamber. The ambient air quality sensor is arranged to sense a property of the ambient air in the vicinity of the system and the controller is connected to the ambient air quality sensor and is configured to receive ambient air quality readings from the ambient air quality sensor and to output an ambient air quality signal based on one or more of the readings of the ambient air quality sensor.

The present invention relates to a system for diagnosis and management of indoor air quality, and more particularly to a system for diagnosis and management of indoor air quality which is capable of obtaining and analyzing air quality data by measuring the indoor air quality of a vehicle or accommodation space and of detecting smoking or non-smoking, the type of smoking, and an abnormal situation by diagnosing at least one of indoor smoking and smoking types.

In addition, the present invention relates to a technology for facilitating the management of accommodation by efficiently diagnosing indoor air quality.
