On detecting a motion, motion sensor would send the signal to panda board GPIO pin which we could read as a file in Linux. Based on the file content which is signal received from motion sensor, we can use system call calls to turn on the display from standby mode to display mode. We can automate all of these activities in a script which will always be running in back ground.The whole system could be customized for different environments like the range of sensor, response time of display by changing script and customizing application software in sensor's MCU.
