Techniques for detecting a high gas pressure situation within a gas delivery system (e.g., for natural gas delivery to homes and businesses) are described. In one example, a device measures gas pressure. If a pressure over a threshold value is detected, a nearby device is messaged. The nearby device either confirms the over-pressure condition or indicates it may be more localized. If the condition is present within an area of the gas delivery system and/or within a group of devices within the gas delivery system, protective measures may be taken, such as closing valves providing gas to a number of service sites.

A control body is coupled or coupleable with a cartridge that is equipped with a heating element and contains an aerosol precursor composition, the control body and cartridge forming an aerosol delivery device. The control body includes a control component to control the heating element to activate and vaporize components of the aerosol precursor composition. The control body also includes a gas sensor configured to detect a presence of gas in an environment of the control body, and the gas sensor or control component are further configured to control operation of at least one functional element of the aerosol delivery device in response to the presence of gas so detected.

An appliance hub for use in an upper portion of an enclosure can include a substrate configured to be positioned in an upper portion of an enclosure. The appliance hub can include a climate control apparatus mounted on the substrate and the climate control apparatus can be configured to regulate a temperature within the enclosure. The appliance hub can include one or more lighting elements configured to provide light within the enclosure, a plurality of fluid lines connected to the substrate and configured to provide fluid service and return to the climate control apparatus, and/or a plurality of electrical connections connected to the substrate and configured to provide electrical power and/or data to at least one of the climate control apparatus and the one or more lighting elements.

A detector device includes a light source disposed within a chamber, a sensor disposed within the chamber, a compensator circuit electrically coupled with the sensor, and a controller. The controller is operable to receive a sensor signal generated by the sensor, determine a compensation factor to adjust the sensor signal, and generate a compensation offset signal based on the compensation factor. The controller is further operable to output the compensation offset signal to the compensator circuit to produce a compensated sensor signal as an adjustment to the sensor signal, energize the light source, monitor the compensated sensor signal with respect to an alarm limit, and trigger an alarm event based on the compensated sensor signal exceeding the alarm limit.

A fugitive gas detection system is provided. The system includes a cloud service, a plurality of reach-based components, a plurality of wireless gas sensors. The reach-based components comprise backhauls and gateways. The wireless gas sensors are acted as nodes to acquire sensor data in a local mesh network and the nodes are connected to the cloud service through the reach-based components, one node can transmit the sensor data to other sensor nodes of the local mesh network. The system measures flammable gas levels with speed, economy and accuracy.
