Figure 3 1 Conceptual Diagram The figure above shows the Conceptual Diagram of the design It shows the theoretical set up of the design The diagram has two images The first image the diagram shows a representation of an intrusion two intruders i e burglars entering through a door The image then points to the other image which is a representation of a mobile phone receiving a text message This image is actually the output or the result of the first image as represented by the arrow pointing to the right Based on this diagram one can infer that the device is triggered once the door or window where the device is placed adjacent to is intruded It immediately sends a notification to the security administrator through an SMS message sent to his mobile number To trigger the device once there is an intrusion it requires a mechanism to indicate such event When actuated by the opening of the door or window it must send a signal to the control circuit indicating an intrusion The control circuit must then immediately notify the security administrator of an impending attack using GSM technology The figure below shows the device in blocks Each block connects to another depending on which block sends and or receives a signal These signals are represented through the direction of the arrows that connect the blocks LCD monitor Microcontroller GSM Modem Figure 3 2 Block Diagram The device accepts the

SMS message the GSM module must first be initialized to text mode AT CFUN 1 AT CMGF 1 Based on Table 3 2 the first line will set the module to phone functionality It has a value of 1 by default so this line may be omitted But in order to make sure the module is set to phone functionality the author included this line in the code The next line will set the module to text mode The GSM module is now set to send text messages Once the GSM module is set to text mode the device should ask the user to input his mobile number Note that this number is the receiver s number not the sender He is instructed by the LCD monitor to do this The device should then receive the user s 11 digit mobile number by using the keypad The keypad should only recognize 11 presses Once the user is done the device stores this 11 digit number as string to the AT command AT CMGS Every time the device sends a text message it uses the number keyed in by the user Then the device asks the user to input a security key The security key allows the device to determine whether it is the security administrator who is entering the house After the input the device now enters a decision It checks whether the microswitch is pressed or not To do this the microswitch is configured normally open Based on the Schematic Diagram Figure 3 3 bit 0 of Port pin 33 to which the microswitches are connected is normally HIGH When a switch is pressed it bec
