    • A data logger that avoids wasting power when data gathering is not needed (or is done by other means), but is activated automatically, without the need for human intervention, when it is needed. The data logger senses and stores data when a primary power source has failed. The data logger includes at least one back-up power source, and a detector switch connected to a primary power source and to one or more back-up power sources, the detector-switch detecting a condition indicative of the primary power source failure state, and connecting at least one back-up power source to provide power to the sampler, the storage medium and the sensor upon detection of the failure condition.
    • 数据记录器,避免在不需要数据收集(或通过其他方式完成)时浪费电力,但是在需要时自动激活,而不需要人为干预。 当主电源出现故障时,数据记录器会检测并存储数据。 数据记录器包括至少一个备用电源和连接到主电源和一个或多个备用电源的检测器开关,检测器开关检测指示主电源故障状态的状态, 以及连接至少一个备用电源,以在检测到故障状况时向采样器,存储介质和传感器提供电力。
