Instructions for use:
1. The reed switch needs to be used together with the magnet. When a certain magnetic force is sensed, it will be in a conducting state. The module outputs a low level. When there is no magnetic force, it is in a disconnected state, and the output is high. The reed switch The sensing distance from the magnet is less than 1.5cm and is not sensitive or triggering;
2. The output terminal of the module DO 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 by the single chip microcomputer;
3. The output terminal of the module DO is connected to the IN end of the relay to form a high-power reed switch, which directly controls the high voltage.
