Claim:
1. A microwave motion sensor having a circuit assembly, for intrusion detection in a predetermined space, the microwave motion sensor comprising: a control unit; a microwave sensing unit coupled to the control unit, for transmitting and receiving a microwave signal; a microwave confining unit, for managing a detection zone of the microwave signal, having an accommodating space formed inside the microwave confining unit, and the microwave sensing unit being disposed inside the accommodating space; and an adjustable means, wherein the circuit assembly is divided into the control unit and the microwave sensing unit, the scope of the detection zone of the microwave signal varies based on the disposed position of the microwave sensing unit and the construction of the microwave confining unit, the construction of the microwave confining unit varies based on the predetermined space; wherein the adjustable means is a telescopic unit integrated with the microwave sensing unit for moving the microwave sensing unit up and down inside the accommodating space, or the adjustable means is a telescopic unit integrated with the microwave confining unit for adjusting the position of the microwave confining unit relative to the microwave sensing unit for managing the scope of the detection zone of the microwave signal.
