Result of experiment shows a good and well behaved system. PIR sensor works well to detect motion and presence of living object. For auto mode, when object comes into detection area of sensor, the lamp will directly turned on in just millisecond. Different when the object comes out from detection range, the system will state several seconds before the lamp turned off. Actually this scenario called a delay scenario and built for system safety. This scenario prevent from very fast lamp triggering, when an object moves one second and leave in one second then the lamp will blinking. For real lamp implementation that event will break internal lamp circuit in a second and the lamp will not working again. So, the delay scenario is very useful to prevent that happening.
