Digital 微波運動感測器 應用多普勒效應來檢測使用微波的移動物體。這與常規紅外(IR)感測器使用的方法不同,因為微波對各種微波反射物體敏感,並且其感測器讀數不受環境溫度的影響。
這種微波感測器廣泛應用於工業,交通運輸和民用領域,如測量車速,液位,自動門運動檢測,自動清洗,生產線材料檢測和汽車倒車感測器等。
The microwave sensor applies the Doppler effect to detect moving objects using microwaves. This differs from the method used by a regular infrared (IR) sensor as microwave is sensitive to a variety of objects that are microwave-reflective, and its sensor readings are not affected by the ambient temperature.
This type of microwave sensor is widely used in industrial, transportation and civil applications such as measuring vehicle speed, liquid levels, automatic door motion detection, automatic washing, production line material detection and car reversing sensors etc.
The microwave detection method has the following advantages compared to other methods:
APPLICATIONS
The microwave sensor can be useful together with other sensors to enhance its measurement accuracy. For example, Microwave sensor could decrease the pseudo fault report rate of human motion detection. And it does a good job in safety & security work.
