Gas sensor controller

An olfactometer or 'electronic nose' is able to vary a plurality of operating parameters during a test cycle in parallel, in accordance with a measurement protocol. The measurement protocol, and correspondingly the operating parameters to be varied, the values to be set for those parameters, and the timing of the variation in these values is tailored to most effectively distinguish between likelycandidates in a particular testing scenario. A characterisation library is then used to match the results of the measurement protocol to the best target in the characterisation library. Test protocolsand/or characterisation libraries may be downloaded from a remote server on demand, and certain activities may be carried out either locally or remotely. 根据测量协议，嗅觉计或"电子鼻"能够在测试周期期间并行改变多个操作参数。调节这种测量协议，以及要改变的对应操作参数、要为这些参数设置的值，以及这些值的变化的定时，以在特定测试情形中的可能候选项之间进行最有效的区分。然后使用表征库将测量协议的结果匹配到表征库中的最佳目标。可以根据需要从远程服务器下载测试协议和/或表征库，并且可以在本地或远程执行特定活动。
