Alarm people have solved some problems, but the alarm on the market for most of them are some large financial institutions, high costs, the general acceptance of it difficulta If the design and manufacture of a cheap and reliable performance of sensitive anti-theft alarm, will guarantee the security and property security to play a more effective rolea In this paper, as the core and a transistor and other electronic technology, to design a touch alarma Choose which time base IC NE555, with R1, C1, C2, C3 monostable multivibrator formed with high sensitivity, fast response, etca, but the low price, small size, long lifea In addition, electronic anti-theft, a
报警器为人们解决了不少问题，但是市场上的报警器大部分都是用于一些大公司财政机构，价格高昂，一般人们难以接受。如果设计和生产一种价廉、性能灵敏可靠的防盗报警器，必将在防盗和保证财产安全方面发挥更加有效的作用。本论文以三极管为核心并与其它电子技术相结合，设计出一种触摸式报警器。其中选用时基集成电路NE555，它与R1、C1、C2、C3组成单稳态触发器，具有灵敏度高、响应快等优点，而且价格低廉、体积小、使用寿命长。此外，在电子防盗、人体探测等领域中触摸式报警器也以其价格低廉、技术性能稳定等特点受到广大用户和专业人士的欢迎。
