A moisture intrusion detection system includes: an industrial robot that has a closed space defined thereinside; an air supply mechanism that supplies compressed air to the closed space; an air vent passage that is provided in the industrial robot to establish communication between an external space outside the industrial robot and the closed space, and guides, to the external space, air ejected from the closed space upon supply of the compressed air; a humidity sensor that detects a humidity of ejected air that is ejected from the air vent passage to the external space upon supply of the compressed air; and a controller that determines presence or absence of moisture intruding into the closed space based on a detected humidity of the ejected air, the detected humidity being detected by the humidity sensor.

The present disclosure provides a fingerprint identification method and apparatus, a storage medium, and a terminal. The fingerprint identification method includes: collecting a to-be-identified fingerprint image of a to-be-identified fingerprint; calculating an image correlation between the to-be-identified fingerprint image and a standard fingerprint image, wherein the standard fingerprint image is a fingerprint image collected from a standard fingerprint; and determining whether the to-be-identified fingerprint is consistent with the standard fingerprint according to the image correlation. The solution provided by the present disclosure can effectively improve the accuracy of fingerprint identification.

A method of controlling a dryer stand, which includes a receptacle on which a dryer for discharging drying air is mounted and which is rotatable in a horizontal direction, and an air purification unit, are provided. The method includes detecting the dryer mounted on the receptacle, charging a battery provided in the dryer when the dryer mounted on the receptacle is detected, determining whether a predetermined condition for air purification operation is satisfied, and operating the air purification unit when it is determined that the predetermined condition for air purification operation is satisfied, whereby it is possible to purify indoor air. A method of controlling the dryer while it is not on the stand is also provided.

A capacitive relative humidity sensor includes a first electrode and a second electrode, where at least the one of the electrodes is a water-permeable electrode. The electrodes act in conjunction with a water-sensitive hygroscopic dielectric material. The design enables low-cost and simple fabrication of fast-responding and stable relative humidity sensors using digital fabrication techniques.
