Today is the 56th year Malaysia commemorating its Hari Merdeka (Independence Day). Persekutuan Tanah Melayu (Federation of Malaya) received their independence from British Colonial on the 31st August 1957. In celebrating this big event, it is incomplete without the flashy and the heavy sound of the massive fire works usually take place at 12 am. However, the powerful sound of the fire works sometimes can trigger the alarm system installed in a car or building. One of the key reason that cause an alarm to be triggered is the sensors inside the alarm system. Common alarm system use pressure sensors and motion detectors. The shock from the fire works sound would triggers these sensors. To overcome this type of false alarm, an advanced sensors that send different information depending on the severity of a shock has been design by Randall Woods. By using this sensor, a warning horn beep or the full-scale alarm can be triggered by different shock force.
