Anti-Bag-Snatching Alarm

Snatch theft is a criminal act of forcefully stealing from a pedestrian's person while employing rob-and-run tactics. Statistics show that most of the victims are women. A growing problem, In some instances of snatch theft have caused fatalities, when the person holding onto the handbag has been dragged by the motorbike or through subsequent acts of violence. The crimes have caused severe injury to head and let them to death. To solve this problem, there are initiatives that have been done by the engineers. This includes on developing a special alarm to avoid from snatch theft to happen. There are three different types of these alarms; hardwired alarm, self-contained alarm and wireless alarm A basic alarm system is divided into parts, which is the main control system, the buzzer, and the sensor. The main control system which is the brain of the device will receive signals from the sensor for analyzing before determine the action that to be taken, whether to turn on the alarm or otherwise. In wireless system alarm, receiver and transmitter units will act as the sensor which is the input, and buzzer as the output of the device. This project will develop based on wireless system alarm, which turn on when detecting the distance between the receiver and transmitter more than 50 meters. if bag goes beyond a range that is beyond the RF module range the system will automatically gives alarm sound.
