An LED dot matrix display consists of a matrix of LED’s arranged in a rectangular configuration. The desired character or graphics can be displayed by switching ON OFF a desired configuration of LED’s. Common display configurations available are 7×5, 8×8, 7×15, etc. LED dot matrix can be used in simple display applications where the resolution is not a big concern. The figure below shows the arrangement of LEDs in a typical 7×5 dot matrix display.Any individual LED or a group of LEDs in the matrix can be activated by switching the required number of rows and columns.

GSM Based Home Security System adopts voice dais of GSM network to send control command and receive alarm distantly. When a signal is perceived by detectors, the detectors will send an alarm signal to system right away. The system then sends alarm to its pre-set mobile phone numbers, and temporarily dials the pre-set telephonemobile phone numbers spontaneously.
