Moving Object Detection In Intelligent Wireless Sensor Network

It is one of the most important fields for the intelligent security system to detect the relatively moving objects, such as people or animals, by some detecting medium infrared ray, microwave, or ultrasonic, which is based on the theory of Doppler to construct the electromagnetic field in the interesting field. When the moving object enters, the detecting medium will produce the reflecting wave from the moving object, which will be detected as a very weak signal through mixing circuit. After processed by a microcontroller, the weak signal will transfer to be a digital voltage to control and drive any other circuits. How to combine this kind of detecting technology with wireless sensor to construct a network is one of the most important points in this paper.WSN (Wireless Sensor Network) is the merging research field with sensors, embedded calculation, and distributed information processing and wireless communication, which has been one of the most active research areas all over the world. The sensor nodes can be located randomly or specifically in the interesting environment, which can obtain the relative...
