Module USES: 1. The dry reed pipe need magnet, when sensing certain magnetic force, will show ON state, the module output low level; no magnetic, show OFF state, output high level, dry reed pipe and magnetic induction distance within 1.5 cm, beyond this distance ,insensitive or will not trigger phenomenon; 2. The module DO output end can connect directly to microcontroller I/O port, triggered by single chip microcomputer can detect dry reed pipe status;it can detect the trigger state of the dry reed by SCM 3. Modules DO output end connect the IN end of relay, can compose high power dry reed pipe switches, control high voltage directly.
