A gas detection apparatus and method for measuring humidity using an electrochemical gas sensor. The gas detection apparatus comprises an electrolyte-based electrochemical gas sensor and a controller configured to measure the average humidity value within an ambient environment over a period of time. The average ambient humidity value over the period of time is determined based on the average rate of change over the period of time of the electrolyte concentration within the electrolyte gas sensor of the gas detection apparatus over the period and the average temperature in the ambient environment over the period of time. The gas sensing apparatus may be configured to communicate the average ambient humidity value within the ambient environment to a second electrochemical gas sensor or a second gas detection apparatus within the same ambient environment.

Method and apparatus for measuring humidity using an electrochemical gas sensor

A method and apparatus are provided to determine the composition of one or more gases. In the context of a method, a sensory assembly and at least one processor, the sensor assembly comprising a first gas sensor and a second gas sensor, includes causing the first sensor to be powered to detect a presence of one or more gas while the second sensor is unpowered. The method further includes detecting the presence of one or more gases while the second sensor is unpowered. In response to detecting the presence of the one or more gases, the method includes causing the second sensor to be powered. The method still further includes capturing sensor data corresponding to at least one of the one or more gases. The method also includes identifying the at least one of the one or more gases based on an analysis of the sensor data.
