At present, almost all of alarm devices are only used for fixing things in the market, while portable alarm devices are inconvenient to carry and expensive, so they are difficult for people to accept. So we designed a small disconnected alarm device through digital circuits .It is mainly composed of triodes, capacitances and the composition of the infrared receiver and has the advantages of adjusting the distance of alarm, sensitive, sounding loud and low power.It can be used for handbags, band cards and other personal things to prevent themselves being stolen.
