title: How many sensors will work at a time in an Arduino for Home automation?
body: <p>As I am thinking to do a Home automation using Arduino, using Light sensor, temperature control , motion sensor , gas leakage sensor , fire detection sensor , hall effect sensor for Light on/off , fan on/off and fan speed control , motion detection , alarm for gas / fire detection , door open/close respectively.
  But my question is how many sensors will work at a time in at an Arduino board?<br>
  And is it possible to control Arduino by using PIC or i.MX6 Dual Lite/Solo?</p>
