The following sub-routine procedure of sending SMS:
In the concept of this system are required to comply with certain aspects of the process that will be carried out in a systematic way, following the performance of the system ketentukan Home security Kata Bijak
Configuring a Phone Number Margahayuland
Phone number is used as the destination number of SMS delivery should be put in the Phone Book numbers (index) one. Because the phone number on this one index number that will be stored by the microcontroller as the destination number SMS delivery.
Telephone number is entered into the HP does not need to use the Indonesian country code example:
Written à +62818309673 0818309673
Here is the writing of a phone number in the Phone Book numbers (index) one:
Figure 2. Writing Phone Number in Phone Book Index 1
In early use, the alarm must be connected to the HP via the data cable before it is turned. The indicator light will light up after the system gets the microcontroller power supply.

Microcontroller will take the phone number from the Phone Book on the first index.
After completion of a phone number microcontroller will start checking every input from the legs of the microcontroller are connected to the sensor. System indicator light will blink indicating microcontroller check each input that is connected to the sensor.
At this alarm system in order to determine whether the alarm system can work well, should do the testing, and the part to be tested on this alarm system is:
This sensor was tested by giving input, through the front of the sensor. Input given by movements in front of the sensor. The motion sensor can be tested while aware of any movement up to a distance up to 6 meters, with no sensor in front of the provisions of any other object blocking the sensor as far as 6 meters. As well as the sensor can determine the movement beside the existing distance of 3 meters with a maximum angle of 55 degrees formed the central point remains effective sensor This sensor detects movement in both dark and light diruang Home security Kata Bijak
Light sensor Margahayuland
It uses a light sensor Light Dependent Resistor (LDR). LDR sensitive to changes in light, the sensor is tested by giving input in the form of light-dark-light changes. When testing the sensor is off a dark room, when the lights come on sensor becomes active.
In the SMS delivery system was tested with an input on one of the sensors, for example: on a motion sensor 1, in doing movement around the sensor, the sensor is active and transmit information in the form of SMS microcontroller via a serial data cable to the HP. In the process of sending this SMS, the SMS is sent to the receiver to + / - 10 Seconds after the sensor is active.
