mOtiOn – The Basic Video-based Motion Sensor
In the past twenty years ago, the motion sensors are particularly very expensive, as a common motion sensor is costs at least several hundreds to thousands of dollars. In addition, it’s impossible to build your very own motion sensor at that moment, due to the lacking of electronic components!
However, the motion sensor is become an inexpensive electronic device, which is built based on real time processing of a video signal using analog preprocessing and optimized image processing algorithms in an AVR ATmega88 microcontroller.
Technically, it can be used to detect movement in an incoming composite video signal in real time at 30 frames per second. Furthermore, it shows where the movement has been detected by simply highlighting it in its video output. As a result, it reports movement through its serial interface and a digital output pin.
With this amazing mOtiOn, you’re allow to mask some sections of each captured frame. The mOtiOn is having the ability to detect and perform on user specified parts. In addition, it has several parameters to filter noise, adjust motion sensitivity, ignore lighting changes and avoid tampering.
The best part about the mOtiOn is the sensor process an analog composite video signal. In this case, it doesn’t need a video decoder chip, which is reducing its cost significantly.
