Reed Switch Sensor Module Magnetron Module Dry Reed Switch for Arduino

DESCRIPTION: Uses:PBX; photocopiers; washing machines; refrigerators; cameras; Disinfection cabinet; door; window magnetic; electromagnetic relay; electronic weighing; level meter; gas meter; water meter and so on have been a very good application.Module Features:1; imported normally open reed switch2; the comparator output; the signal is clean; the waveform; driving ability; more than 15mA.3; operating voltage 3.3V-5V4; the output in the form: Digital switching outputs (0 and 1)5; a fixed bolt hole for easy installation6 small board PCB size: 3.2cm x 1.4cm7; wide voltage LM393 comparatorReed switch features:Reed switch is an abbreviation of the dry reed contacts a passive electronic switching elements; and has the advantages of simple structure; small size and ease of control; its shell is a sealed glass tube; the tubes are installed two iron elastic reed plate; but also filling called rhodium metal inert gas. In peacetime; the glass tube in the two reeds is made of special materials are separated. When a magnetic substance close to the glass tube; in the role of the magnetic field lines; the pipe within the two reeds are magnetized to attract each other in contact; the reed will suck together; so that the junction point of the connected circuit communication. After the disappearance of the outer magnetic reed because of their flexibility and separate; the line is disconnected. Therefore; as a use of the magnetic field signals to control the line switching device; reed tube can be used as a sensor for counting the number; spacing; etc. (in the security system is mainly used for production of Menci; magnetic window); and also are widely used in a variety of communication devices. In practical use; usually with a permanent magnet control two metal sheet is turned or not; it is also referred to as 'magnetron'.Module using the instructions:Dry reed and the magnet with the use; to a certain magnetic induction will be presented to the conduction state; the module output low; no magnetic force; and the OFF state; the output high; reed the magnet sensing distance of 1.5cm beyond insensitive or will trigger phenomenon;2 module DO output of the microcontroller the I / O ports directly connected to the reed switch triggering state can be detected through the microcontroller;3. Connected to the module DO output relay IN the end; composed of high-power reed switch; high voltage direct control. INCLUDED: 1 x Reed Switch Sensor Module
