The design of alarm system for the high sensitivity and detention type touches

Abstract: This design is the highly sensitive and type touches of the burglar alarm, It introduced this circuit of alarm system principle of work and realized the function in detail, and have carried on the detailed description to the electric circuit structure and the principle. The system is composed by the power circuit, touches switch electric circuit. This burglar alarm has the structure simple, the work stable reliable, the volume is small, the manufacture and the installment quickly and so on .the characteristic cannot appear reports mistakenly the phenomenon, It is one kind of the practical simple electronic burglar alarm.
Key word: alarm; safety guard against theft; touch alarm
