A hot wire sensor is provided to detect moving objects radiating far infrared rays conveniently, and to secure a detecting region which detects movement of the objects easily. A hot wire sensor includes a lens unit receiving member(120), a main body(110), and an adjusting part(121a). The lens unit receiving member accommodates movement of objects. The main body is combined on the lens unit receiving member. The adjusting part prevents separation of the lens unit receiving member from the main body. The adjusting part fixes and rotates a lens unit to adjust a movement detecting region of the lens unit. |
