Energy Efficient Smart Wireless Sensor Network for Border Monitoring	2019	11	.pdf	application/pdf	2178	99	59	The main idea of the proposed system The main idea of the proposed system as shown in Figure (1) is based on controlling three different kinds of sensors, PIR sensor which is the primary sensor of the system, acoustic sensor, and magnetic sensors using two techniques the monitoring cycle, and the power gating technique Every fifty seconds the system deactivates the power gating of the PIR sensor and connects it to the energy harvest- ing source, the PIR sensor is ON for ten seconds, if the output of the PIR sensor is less than Vth then PIR sensor goes OFF again for a new monitoring cycle, and if the output of the PIR sensor is greater than Vth the sensor remains ON and the system deactivates the power gating of the other two sensors (acoustic and magnetic) and the output of the three sensors are then connected to the fuzzy system controller, which gives the suitable action for the corresponding output, the system then is being reset by the operator and the cycle is repeated. Figure(10) represents the rule View of Input and the calculated outputs according to the inputs, for example when the inputs of the three sensors are 2.5V for PIR sensor, 1.5V for acoustic sensor, and 1.5V for magnetic sensors the outputs will be 11.5 for no danger, 48.5 for animals, 30 for human, and 30 for vehicle.	cache/archive-387.pdf	txt/archive-387.txt
