Specifications:

Reed is a short dry reed, is a kind of passive electronic switch contact element has a simple structure, small size and easy to control, etc., the shell is generally a sealed glass tube which is installed there are two flexible iron reed panels, also called metal rhodium is filled with inert gas. Normally, two glass tubes made from special materials are separated.When a magnetic substance is placed near the glass tube, under the influence of magnetic field lines, the two reed tubes become magnetized and attract each other. The reeds move closer together to form a communication circuit at the connected node.After the external magnetic force disappears, the two reeds separate due to their elasticity, and the line also disconnects.Therefore, as a signal to control the use of magnetic field line switching devices, the reed can be used as a sensor for counting, spacing, etc.(In security systems, it is mainly used for door sensors and magnetic window sensors), but it is also widely used in a variety of communication devices.In practice, typically with a permanent magnet controlling the two metal plates (on or off), it is also known as a "magnetron".

USES of the module:
1. Dry reed pipe needs magnet, when detecting a certain magnetic force, will display ON state, module output level is low; no magnetic, shutdown state, high output level, dry reed pipe and magnetic induction distance less than 1.5cm, beyond this distance, insensitive or will not trigger phenomenon;
2. The output end of the DO module can directly connect to the I/O port of the microcontroller, triggered by a single-chip microcomputer which can detect the state of the dry reed pipe; It can detect the trigger state of dry reed by SCM
3.The DO output end modules connect to the IN end of the relay, can be used to create high-power dry pipe reed switches, and directly control high voltage.
