With the continuous progress of soc

With the continuous progress of society, science and technology, and economic development, people's living standards have been greatly improved, and the awareness of private property protection has been constantly enhanced, so new requirements for anti-theft measures have been put forward. This design is to meet the needs of modern residential anti-theft design of the home type electronic anti-theft system. At present, there are many kinds of alarms on the market, such as pressure triggered alarm, switch electronic alarm and pressure blackout triggered alarm, but these alarms have some shortcomings. The infrared ray used in this design is invisible light, which has strong concealment and confidentiality, so it has been widely used in security devices such as anti-theft and alert. The pyroelectric infrared sensor can detect the infrared radiation of human body in the form of non-contact and transform it into voltage signal. At the same time, the pyroelectric infrared sensor can be used not only in anti-theft alarm device, but also in brake control, proximity switch, telemetry and other fields.With the improvement of living standards, especially in today's technology and material life, people pay more and more attention to their property security. Family safety has become the latest and hottest market demand in the 21st century. Science and technology is a double-edged sword. Today, with a large population flow, it has increased a lot of problems and put forward greater requirements for family anti-theft. Traditional anti-theft measures, such as anti-theft doors and windows, have been difficult to meet the needs of the development of modern society. With the development of science and technology, people put forward new requirements for family security measures. From the traditional anti-theft measures to the intelligent home anti-theft alarm, to the present remote intelligent home anti-theft alarm. People's intelligent life continues to pursue, the previously remote technology products, in the rapid development of science and technology today, are not a problem. The products of family security have excellent performance, low false alarm rate, good quality, and the price has been reduced from the sky price to the civilian price.
