The field of the present invention generally relates to a real-time methane detection system that provides measurement, monitoring, and alarm notification of a methane leak. This invention also generally relates to automatic shutoff of a compatible gas valve in response to methane at or above a pre-determined threshold such as an explosive level. Additionally, this invention generally relates to authentication, communication, notification, alarm, and other information between a methane detection device, a compatible gas valve located at a pre-determined geographical location, such as a home address, a user, optionally a gas utility, and optionally a compatible gas valve manufacturer.
Methane, a component of natural gas, is more efficient and cheaper than electricity for heating and cooking and is used in household appliances such as natural gas furnaces, space heaters, water heaters, and stoves. However, gas supply pipes and gas appliances have the potential to malfunction, leak, and send gas throughout the home having a variety of effects on those living within the home and on the home itself such as health effects, asphyxiation, and explosion hazard.
Natural gas leaks typically emit a rotten-egg smell throughout the house; however, a gas leak may be small and steady such that the rotten-egg smell is undetectable. Additionally, the rotten-egg smell can dissipate over time also making it undetectable or lead people to assume incorrectly that the problem has been resolved. Another sign of a gas leak is a hissing sound that may be coming from the damaged line or appliance that is causing the problem. Symptoms of natural gas poisoning include gastrointestinal problems, an increase in allergic reactions, fatigue, forgetfulness, high red and white blood cell counts, migraines, pain and discomfort.
Existing natural gas detectors, including methane detectors, are different than smoke or CO2 detectors and are generally installed by plugging into a wall outlet located close to the floor. Installation of the gas detector down low is ineffective as methane is lighter than air and rises. Existing gas detectors also use an ineffective chemical sensor that gives false positives in the presence of many household volatile organic chemicals (VOCs) such as cleaning products, hair products, hairspray, furniture polish, room disinfectant, deodorant, and fabric refresher. Any false positives may lead to consumers not trusting the gas detector or consumers ignoring alarms from the gas detector when there is an actual gas leak. Additionally, some gas detectors require calibration leading to decreased effectiveness of the gas detector if not calibrated or replacement leading to increased costs for a property owner to monitor for gas leaks.
However, the greatest risk, the risk of explosion to both the property owner and surrounding neighbors is increased when windows and doors are closed and there is no one home to smell the gas leak, hear an alarm from a gas detector, or take action to notify emergency personal or a gas utility.

The present invention provides among other things a residential methane detector (RMD) that when installed and powered on communicates with a user's mobile device for authentication, setup, and preferences and with a sever for authentication and monitoring such as by cellular, Wi-Fi, near-field, LoRa, Bluetooth, another communication protocol, or combination of communication protocols. Implementations of the present invention may provide for the server to communicate and establish a connection with a compatible gas valve by a pre-defined communication protocol then the server notifies a gas utility of the compatible gas valve and optionally notifies a gas valve manufacturer of the compatible gas valve. Particular aspects of the present invention may provide for the server to continuously monitor the health and state of the RMD such as by monitoring the constant time intervals of a live RMD by a network such as a cellular network. Particular aspects of the present invention may provide for the RMD and/or the server to optionally notify the user, gas utility, and/or gas valve manufacturer if the RMD, the compatible gas valve, or residential methane detection system goes offline (such as an RMD that is no longer live). Particular aspects of the present invention may provide for the practical application of the detection and real-time monitoring and communication of potential gas leaks brought about by computerized technology such as the internet-of-things (IoT) and automatic notifications both locally and remote from the methane gas detection hardware.
Implementations of the present invention may provide for the RMD to measure continuously for a methane leak and communicate real-time information related to the RMD and measured methane levels to the server and if the RMD or the server determines that a methane level is at about or above a pre-determined threshold, the RMD will alarm such as with a loud audio or spoken message. Particular aspects of the present invention may include if the RMD or the server determines that a methane level is at about or above a pre-determined threshold, the RMD and/or the server may notify the gas utility, user, and emergency services and optionally provide information related the urgency of the methane levels and location information such as a physical location, such as an address, where the gas leak was detected. Particular aspects of the present invention also provide for more than the detection of methane gas by integration of hardware capable of effective and stable methane detection system located near a potential gas leak with local and remote communication, monitoring, and alarm protocols including transmitting real-time gas detection data and automating emergency services.
Implementations of the present invention may include that if the RMD and/or the server determine that a methane level is at about or above a pre-determined threshold, the RMD, the user, the server, the gas utility, the compatible gas valve manufacture, or another third party may shut down the connected gas valve.
