Dry reed pipe needs and magnet is used together, in the induction to have certain magnetic, a conducting state, module output low level, no magnetic, is off state, output high level, dry reed pipe and magnetic induction distance within in 1.5 cm beyond insensitive or will not trigger phenomenon. Module DO output end of the single chip microcomputer can I/O port directly connected, through the single chip microcomputer can detect dry reed pipe state trigger. Module DO output end and relay IN end connected to form high power dry reed pipe switch, direct control high voltage.
