Abstract: A gas sensor includes a plurality of sensing resistors that vary in resistance based on ambient temperature and the presence of certain gases, such as CO2 and H2O. The responses of each of the sensing resistors vary based on a base temperature of each of the sensing resistors. The base temperatures for each of the sensing resistors and configurations of the sensing resistors are selected to emphasize a response to a gas of interest (e.g., CO2) while de-emphasizing or canceling contributions from ambient temperature and gases that are not of interest (e.g., H2O).

Abstract: Systems and methods monitor a space for environmental pollutants. A sensing device senses and reports air quality anomalies to a cloud detection service. The cloud detection service uses artificial intelligence to analyze raw sensor data from the sensing device, determines whether the raw sensor data indicates an air quality event, and sends an air quality report indicative of the air quality event to a client device associated with the sensing device and/or the monitored space. A sensing device may be deployed in an air extraction vent to detect and report indications of vaping in prohibited spaces. A sensing device may be deployed in a vehicle to detect and report smoking in vehicles where smoking is prohibited. An application running on a mobile device reports detection of a short-range wireless beacon within a serviceable space to a cloud detection service, which tracks servicing of the serviceable space.
