In one aspect, there is provided a moisture detection system that includes: a moisture detection unit including: a moisture sensor configured to obtain a measurement that indicates an amount of moisture, and a Radio Frequency Identification (RFID) module coupled to the moisture sensor through multiple wires, where the RFID module includes an antenna and is configured to wirelessly transmit a telemetry message based on the measurement from the moisture sensor through the antenna and is further configured to wirelessly receive energy for powering the moisture detection unit through the antenna; and a control unit communicatively coupled to the moisture detection unit, where the control unit is configured to wirelessly receive the telemetry message from the RFID module and process the telemetry message to determine the amount of moisture measured by the moisture sensor.

A power supply device is provided. The power supply device includes a housing, a power converter, a controller, multiple humidity sensitive capacitors, and a feedback circuit. The housing has multiple joints. The controller controls the power converter to provide an output voltage. The humidity sensitive capacitors are respectively configured in the housing and adjacent to a corresponding joint of the joints. The humidity sensitive capacitors jointly provide a sensing capacitance value. The feedback circuit changes a gain value and a compensation bandwidth of the output voltage in response to the change of the sensing capacitance value. When the humidity of at least one of the joints increases, the sensing capacitance value is reduced, so that the gain value and the compensation bandwidth are reduced.

In some respects, concepts disclosed herein generally concern systems, methods and components to detect a presence of a liquid externally of a desired primary flow path through a segment of a fluid circuit, e.g., throughout a cooling loop. Some disclosed concepts pertain to systems, methods, and components to direct seepage or leakage of a liquid coolant toward a lead-detection sensor. As but one example, some disclosed liquid-cooled heat exchangers incorporate a leak-detection sensor, which, in turn, can couple with a computing environment that monitors for detected leaks, and, responsive to an indication of a detected leak, invokes a task to control or to mitigate the detected leak.

A battery pack which includes: a battery cell which contains a non-aqueous electrolyte, wherein the battery cell is a non-aqueous electrolyte secondary battery; a casing which stores the battery cell; and at least one liquid leakage sensor which detects liquid leakage from the battery cell, wherein the casing and/or the battery cell have a leaked liquid retention region in which the non-aqueous electrolyte tends to be retained when the non-aqueous electrolyte leaks out of the battery cell, wherein the liquid leakage sensor outputs measurement information as a detection result without using a charging/discharging circuit which charges and discharges the battery cell, and wherein at least one sensor unit of the liquid leakage sensor is provided in the leaked liquid retention region.

An apparatus and a method of detecting liquid leakage within a battery pack using a gyro sensor and a moisture detecting sensor. When liquid leakage of a coolant is detected, such as when a pipe of a coolant supplied for cooling (radiating heat) within a battery pack is damaged, the apparatus recognizes a liquid leakage generation position according to a slope of the battery pack by using a gyro sensor and determines whether the liquid leakage is generated based on a difference in a temperature between an upper side and a lower side of a corresponding region by using moisture detecting sensors, thereby improving accuracy of the detection of the liquid leakage according to the slope and the position of the battery pack. Particularly, the moisture detecting sensor is operated to be on only when the detection of the liquid leakage is required, thereby preventing unnecessary energy consumption.
