characteristics of dry reed:
dry reed switch is the abbreviation of dry reed switch. It is a passive electronic switching element with contacts. It has the advantages of simple structure, small size and easy control. Its shell is generally a sealed glass tube with two iron tubes. The elastic reed plate is also filled with an inert gas called metal rhodium. Usually, the two reeds made of special materials in the glass tube are separated. When a magnetic substance is close to the glass tube, under the action of the magnetic field lines of force, the two reeds in the tube are magnetized and attracted to each other, and the reeds will be attracted together to connect the circuit connected to the node. After the external magnetic force disappears, the two reeds are separated due to their own elasticity, and the line is disconnected. Therefore, as a magnetic field signal to control the line switching device, dry reed switch can be used as a sensor for counting, limit, etc. (in the security system is mainly used for door magnetic, window magnetic production), but also widely used in a variety of communication equipment. In practice, magnets are usually used to control the connection of these two metal sheets, so they are also called "magnetrons".
Instructions for use of the module:

1. The dry reed switch needs to be used in conjunction 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 will be in an off state and output a high level. The sensing distance between the dry reed switch and the magnet is within 1.5cm beyond insensitivity or there will be no triggering phenomenon;

2. The output end of the module DO can be directly connected to the I/O port of the microcontroller, and the trigger state of the reed switch can be detected by the microcontroller;

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