Gas Measurement Device Incorporated Into a Watch

Abstract

A device for measuring the concentration of a gas constituting the ambient air includes a wristwatch comprising a watch case (13) containing a watch movement, members indicating the time (1, 3, 9) visible through a glass of the watch case (13). In addition, the wristwatch comprises at least one sensor (11) arranged to measure the concentration of a gas constituting the ambient air. The wristwatch also includes means for actuating an alert when reaching or exceeding a threshold of the gas concentration measured by the sensor (11). The device includes two operating states, a “time” state and an “alarm” state, wherein in the “time” state, the members indicating the time (1, 1′, 3, 9) indicate the time and the sensor (11) permanently measures the gas concentration without displaying it or activating the alert. In case where the sensor (11) detects a concentration of a gas, the device switches to the “alert” state wherein the indicator member (4, 4′, 8, 9, 10) displays this measured value and/or the means for actuating an alert actuate an alert normally without the time being displayed.

 a wristwatch; and   an external apparatus,   wherein the wristwatch includes,
 a casing; 
 a display; 
 a gas sensor configured to measure a concentration of a gas in ambient air; 
 a device for generating an alert; and 
 a wireless communication device for transmitting information to the external apparatus, 
   wherein in a case a threshold of the concentration of the gas measured by the gas sensor is reached or exceeded, the device for generating an alert generates an alert, and   wherein the wireless communication device is configured to transmit information that the threshold of the measured gas concentration has been reached or exceeded to the external apparatus.   
     
     
         37 : The gas detection system according to  claim 36 , wherein the external apparatus includes a smartphone or a PC.
