131. Furthermore, a burglar may want to break the door of your house while barging in. You also might have to cope with broken windows, smashed furniture and other general damage. Making up for this damage will be expensive not just time wise but also requires great deal of effort since burglars these days are interested in expensive items. They search for important identifications such as your bank statements, passports, and credit cards, essentially whatever they get their hands on. The misuse of these documents will disturb your economic balance. Therefore, it is recommended to install a home alarm system at your place. Sensors are the most vital part of the system; they act like the eyes and ears of a home alarm system by monitoring break in points and interior areas. The typical sensors, which are usually two magnets, are generally installed on doors and windows such that one magnet is connected to the door or window and the other is connected to the door or window frame. When the door or window is opened, one magnet is removed from the surrounding area of the other and the sensor registers that the door has been opened. More advanced home alarm systems may also contain vibration sensors to detect when glass has been broken by measuring the vibrations caused by the breakage.

They are popular with both professional developers and hobbyists alike due to their low cost, wide availability and large user base. The PIC has an overall of 40 pins. These pins include input/output ports such as PORTA, PORTB, PORTC, PORTD, PORTE and two Vdd ports for input voltage. The PIC architecture is characterized by its multiple attributes:Separate code and data spaces Harvard architecture. A small number of fixed length instructions. Most instructions are single cycle execution, with one delay cycle on branches and skips. All RAM locations function as registers as both source and destination of math and other functions.
