Module using the instructions
1.Dry reed and the magnet with the use, to a certain magnetic induction will be presented to the conduction state, the module output low, no magnetic force, and the OFF state, the output high, reed the magnet sensing distance of 1.5cm beyond insensitive or will trigger phenomenon;
2.Module DO output of the microcontroller the I / O ports directly connected to the reed switch triggering state can be detected through the microcontroller;
3.Connected to the module DO output relay IN the end, composed of high-power reed switch, high voltage direct
control.
