Characteristics of dry spring tube:
Dry reed tube is short for dry tongue reed tube, is a passive electronic switching element with contact, has the advantages of simple structure, small volume and easy to control, its shell is generally a sealed glass tube, tube with two iron elastic reed plate, but also filled with a metal rhodium inert gas. Normally, the two reeds in the glass tube, made of a special material, are separated. When there is a magnetic material near the glass tube, under the action of the magnetic field line, the two reeds in the tube are magnetized and attracted to contact each other, and the reeds will be drawn together to make the circuit connected to the node connected. When the external magnetic force disappears, the two reeds are separated by their own elasticity, and the line is disconnected. Therefore, as a magnetic field signal to control the line switch device, dry reed tube can be used as a sensor, used for counting, limit and so on (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, the magnet is usually used to control the connection of the two metal pieces, so it is also called "magnetron".
Module instructions:
 
1. The reed tube needs to be used in conjunction with the magnet. When there is a certain magnetic force induced, it will be in the on-state, the module outputs low level, and when there is no magnetic force, it is in the disconnected state and outputs high level.
 
2. The DO output terminal of the module can be directly connected to the I/O port of the single chip microcomputer, through which the trigger state of the dry spring tube can be detected;
 
3. The DO output end of the module is connected with the IN end of the relay to form a high-power reed switch to directly control the high voltage.
