The present invention relates to a detachable object sensing apparatus, and more particularly, to a detachable object sensing apparatus which includes a housing having an upper surface opened and having a first accommodating space for accommodating an electronic board and a second accommodating space for accommodating a battery adjacent to the first accommodating space; A sensor housing that forms a fixing part for fixing the object detection sensor on the protruding surface by having a protruding surface protruding upwardly from the upper surface to protect the electronic substrate by closing the first storage space by being slidably coupled along one side of the housing, government; A sensor protection cover covering the sensor fixing part; A detachment fixture coupled to a lower surface of the housing and detachably attached to the attachment position; And a battery cover which is slidably coupled along the other side of the housing and covers the second storage space. The electronic device according to claim 1, further comprising a battery cover And at least one of a device or a vibrator. According to the present invention, the ultrasonic sensor is firmly attached to the housing and can be detachably attached to the outside with a detachable fastener that can be detachably attached to the outside. Accordingly, when an object of the outside environment is required to be detected, such as a visually impaired person, the frontal object is previously notified as vibration or sound, so that a collision accident can be prevented beforehand, thereby protecting the disabled person safely.본 발명은 탈부착 물체 감지장치에 관한 것으로서, 상면이 개방되며, 전자기판을 수납하는 제1 수납공간과 제1 수납공간에 이웃하여 배터리를 수납하는 제2 수납공간이 형성된 하우징; 하우징의 일측을 따라 슬라이딩 결합되어 제1 수납공간을 폐쇄시켜 상기 전자기판을 보호하며, 상면에 상방향으로 돌출되는 돌출면을 구비하여 돌출면에 물체감지 센서를 고정하는 고정부를 형성하는 센서 고정부; 센서 고정부를 커버하는 센서보호 커버; 하우징의 하면에 결합되어 부착위치에 탈부착되는 탈부착 고정구; 및 하우징의 타측을 따라 슬라이딩 결합되어 상기 제2 수납공간을 커버하는 배터리 커버;를 포함하며, 물체감지 센서의 전방 감지에 따라 전방에 물체가 있음을 부저음 또는 진동으로 제공할 수 있도록 전자기판에 음향장치
