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.

According to the conventional knowledge, a thermal humidity measurement device has problems in which the direction of air flow is limited to one direction is too hard to handle in securing the humidity responsiveness because there are limitations on the mounting direction of the thermal humidity measurement device and the state of air flow. An introduction guide protrudes from an air introduction surface to the outside of a measurement chamber, is parallel to a humidity introduction port surface, and has a portion not in contact with an inlet surface of a humidity introduction tube as seen from any direction to guide the flow of air to the humidity introduction tube from any direction of 360°.

The inventive concept relates to a method of determining the relative ratios or percentages of certain characteristics or properties of viscous substances, wherein moisture content is a key determinant. The method utilizes placement of passive Radio Frequency Identification (RFID) instrumentation into a slurry or existing viscous mixture of substances. The RFID then reads moisture and/or other physical properties of the substance, typically process parameters such as temperature and/or pH. The readings are queried using an interrogator to acquire the data wirelessly. As a planning step, it is necessary to correlate the data with a variety of specially-developed algorithms specific to a viscous mixture associated with a particular process. The acquired readings will then provide a user with instantaneous information which will be determinative of the degree of completeness or maintenance of a certain property of the process.
