Module instructions:

1. The reed switch needs to be used in conjunction with a magnet. When a certain magnetic force is sensed, it will be in a conducting state. The module will output low level. When there is no magnetic force, it will be in an off state and output high level. The sensing distance between the magnet and the magnet is within 1.5cm. It is not sensitive or there will be no trigger phenomenon;

2. The DO output of the module can be directly connected to the I/O port of the single-chip microcomputer, and the trigger state of the reed switch can be detected through the single-chip microcomputer;

3. The DO output terminal of the module is connected to the IN terminal of the relay to form a high-power reed switch, which directly controls high voltage.
