Features of Reed Pipe:
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, which is installed in the tube. There are two iron elastic reed plates, and it is filled with an inert gas called rhodium. Usually, the two reeds made of special materials in the glass tube are separated. When a magnetic substance approaches the glass tube, under the action of the magnetic field lines, the two reeds in the tube are magnetized and attracted to each other, and the reeds will attract 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 circuit is also disconnected. Therefore, as a line switch device controlled by a magnetic field signal, the reed switch can be used as a sensor for counting, limiting, etc. (in the security system, it is mainly used for the production of door and window magnets). It is widely used in various communication devices. In practical applications, permanent magnets are usually used to control whether the two metal pieces are connected or not, so they are also called "magnetrons."
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 a disconnected 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 with the IN terminal of the relay to form a high-power reed switch, which directly controls high voltage.
