The housing is substantially sealed for preventing the ingress of debris into the housing, and the housing is configured such that air is able to flow into the housing and over the first sensor.

A method includes attaching a gas capture device to a bypass system adjacent to a gas meter. The method also includes rotating an internal cartridge near the gas meter to a bypass mode. The rotation of the internal cartridge enables gas to be diverted through a bypass system and away from the gas meter into an outlet. Remaining gas is captured from the gas meter to prevent the gas from releasing externally. The gas meter is removed from its original position. The internal cartridge is rotated from the bypass mode to a purge mode.

A device for detecting gas and controlling volume of clean gas includes a gas detection module and a gas guider. The gas detection module includes a control circuit board, a gas detection main part and a microprocessor, wherein the gas detection main part detects a gas to generate a signal and transmits the signal to the microprocessor for calculating and processing so as to generate a gas detection data, and the microprocessor outputs a power signal and a pulse-width modulation (PWM) signal according to the gas detection data. The gas guider receives the power signal and the PWM signal outputted by the microprocessor, the gas guider is enabled or disabled, as well as a rotation speed and an output volume of clean gas of the at least one gas guider are adjusted according to the power signal and the PWM signal.

A personal air quality detection device is configured to monitor the air quality of a user based on the location of the personal air quality detection device. To this end, the personal air quality detection device first determines a location of the user. Based on the determined location, the personal air quality detection device selects a location profile associated with the determined location indicating one or more substance threshold values. Using a substance threshold value indicated by the location profile, the personal air quality detection device monitors the location for a substance of interest by comparing a measurement of the substance of interest to the substance threshold value. Based on the comparison, the personal air quality detection device displays one or more notifications associated with the substance of interest.

The present invention relates to a gas measuring system for measuring the presence of a predetermined gas including a light source and a light receiver separated by a gas volume, the light source emitting light within a chosen range of wavelengths including characteristic absorption wavelengths of the gas to be measured and the light receiver being capable of detecting light in said wavelength range and the system including a spectrum analyzer and a storage means for storing the specific absorption wavelengths of the gas thus to recognize a gas absorbing at said specific wavelengths.
