    The present invention relates to gas measuring devices.
    The dangers due to gases can have different origins such as for example a leak of one or more toxic gases, a deficiency or too high a concentration of oxygen, or the presence of flammable gases. If it is not detected early, staff, premises and equipment can not be protected.
    Depending on the need, it may be necessary to choose a very specific detector or on the contrary capable of detecting a wide variety of gases.
    The main risks that arise from the presence of gas are an explosion due to the presence of flammable gases and intoxication or asphyxiation due to the presence of toxic gases.
    [0005] A gas detector may therefore be necessary as an individual protection for activities exposed to a risk. Portable gas detectors can meet one-off business needs, or in many industrial applications, safety must be continuously ensured by a stationary gas detection system.
    The need to measure at the same time and continuously the concentration of several gases is increasingly common in industrial applications (chemical and food industries but also boiler rooms, tunnels ...)
    The toxic gases come from various sources, such as for example combustion (CO-NO-NO2-SO2), incineration (H2S-NH3-HCl) or fermentation (H2S-NH3).
    [0008] Their presence, passive or active, in an industrial environment is frequent (chemistry, petrochemicals, cold chains, food processing) and makes their detection essential. The risks of intoxication are related to the exposure time of a subject to a harmful product. The danger is assessed in terms of average exposure value and exposure limit value. These values are expressed both in weight (mg / m3) and in volume (part per million, ppm).
    The portable gas detectors make it possible to know whether the ambient atmosphere is explosive or not, which is fundamental for the safety of the first responders on a fire, for example. The danger of explosion caused by this or that gas is often underestimated and the operator must rely on an apparatus for detection and measurement of explosiveness, compact, reliable, and easy to implement.
    The main disadvantage of these portable devices is that they must be worn in a place at risk and they are often deposited as soon as the risk area is left. Therefore, a person may end up in an area presumed to be safe, such as his home, and be exposed to the presence of a toxic gas such as carbon monoxide.
    The purpose of the present invention is to provide an alternative to all these devices, and more particularly, to provide a wristwatch with a gas detector that can measure the concentration of gas in risk areas, as in areas that are thought to be safe.
    According to the invention, a device for measuring the concentration of a gas comprising the ambient air comprises a wristwatch comprising a watch case containing a watch movement, indicating organs of the time visible through a ice of the watch box. In addition, the wristwatch includes at least one sensor arranged to measure the concentration of a component gas of ambient air, this sensor being located in a housing of the watch case or an element attached to the box. shows and has a surface inside this housing exposed to ambient air through at least one orifice, the orifice being on a part of the watch case or on the insert which is not in contact with the wrist of the wearer when the wristwatch is worn on the wrist. The wristwatch also comprises means for actuating an alert when reaching or crossing a threshold of the gas concentration measured by the sensor.
    In one embodiment, the wristwatch comprises an indicator member of the measured value of the gas concentration, this indicator member to know the value of the instantaneously measured gas concentration.
    The indicator member of the measured value of the gas concentration can also also indicate the maximum value of the measured gas concentration.
    In a variant, the wristwatch may comprise a sensor for measuring the value of the gas concentration measured instantaneously and means for actuating an alert when reaching or crossing a threshold of the gas concentration. measured by the sensor without the wearer of the wristwatch knowing the concentration reached.
    In a preferred embodiment, the watch comprises alert means such as a light alarm and / or an audible alarm and / or a vibrating alarm.
    Alternatively, the means of the wristwatch comprises a wireless communication means for transmitting information to another device, including a smartphone or computer, such as information that the threshold of concentration measured gas has been reached or exceeded.
    In another embodiment, the wristwatch comprises a control unit arranged to measure the operating state and / or the life of components integrated in the watch case, including the sensor or the duration life of a power source.
    In one embodiment, the wristwatch may comprise a storage unit arranged to keep a history of the measured values of the gas concentration and optionally the measurements of the components integrated in the watch case and inspected by a unit. control. For example, the watch can record in this storage unit a history of concentrations, exposure times, gas concentration profiles during an exposure, a maximum concentration during an exposure, a number of exposures, a duration of life of the power sources, a lifetime of the sensor. All this information can be accessible to the user either directly on a display of the watch, or by a remote device such as a smartphone.
    According to this embodiment, the actuating means of an alert can be engaged when the control unit indicates that at least one component integrated in the watch case requires external intervention.
    The wristwatch may include needles for displaying the time and the same needles or other needles for displaying the measured value of the gas concentration.
    In a variant, the wristwatch may include a digital display for displaying the time and the same digital display or another digital display for displaying the measured value of the gas concentration.
    In a combined display version, the wristwatch may include hands for displaying the time and a digital display to display the measured value of the measured gas concentration and vice versa.
    For ease of maintenance, the wristwatch may include a processing unit adapted to receive information from an external device for example a smartphone or a PC to configure the watch, in particular to calibrate the sensor or for a setting up to date.
    In one embodiment, the wristwatch may comprise, inside the watch case, a transmitter for transmitting information and a receiver for receiving information. Thus, a wireless communication can in particular to manage the configuration of the watch, transmit alarms, transfer the internal data of the watch as an initialization and a setting of the watch, a time setting of the watch. Other functions, such as alarm transmission, memory data transfer, or calibration and calibration of a gas sensor can be performed.
    Depending on the needs, the watch may include a plurality of sensors arranged to respectively measure the concentration of a particular gas component of the ambient air. The watch can be equipped with sensors to detect for example hydrogen sulfide, or carbon monoxide.
