An ultraviolet sterilization device used in a compartment for personnel to enter and exit, including: a microcomputer with functions of arithmetic processing and control； an infrared sensor electrically connected to the microcomputer； a vibration sensor with electrical properties Connected to the microcomputer； and an ultraviolet module electrically connected to the microcomputer； wherein the microcomputer has a control logic. When the microcomputer executes the control logic, the infrared sensor does not sense human infrared or When the animal infrared rays and the vibration sensor does not sense the vibration, the ultraviolet module is controlled to turn on and emit ultraviolet light； when the infrared sensor detects human infrared rays or animal infrared rays, or the vibration sensor senses When vibration is detected, the UV module is controlled to be closed without emitting UV light.一種使用於可供人員進出的廂室之紫外線殺菌裝置，包含有：一微電腦，具有運算處理以及控制的功能；一紅外線感測器，電性連接於該微電腦；一震動感測器，電性連接於該微電腦；以及一紫外線模組，電性連接於該微電腦；其中，該微電腦具有一控制邏輯，於該微電腦執行該控制邏輯時，係在該紅外線感測器未感測到人體紅外線或動物紅外線、且該震動感測器沒有感測到震動時，即控制該紫外線模組開啟而發出紫外線光；在該紅外線感測器感測到人體紅外線或動物紅外線，或該震動感測器感測到震動時，即控制該紫外線模組關閉而不發出紫外線光。
