10pcs/lot Reed Sensor Module Magnetron Module Reed Switch Magnetic Switch For Arduino

Normally, two glass tubes made of special materials reeds are separated. When a magnetic substance near the glass tube, under the action of magnetic field lines, the two reed pipe is magnetized and attract each other contacts, the reed will pull together to make a circuit of the connected node communication. Specification: Working voltage of 3.3V-5V Type:Normally-open Comparator : LM393 Output Type : Digital output (0 and 1) PCB board size: 3.2*1.4cm/1.3*0.6in Weight: Approx.13g/0.5oz Module USES: 1. The dry reed pipe need magnet, when sensing certain magnetic force, will show ON state, the module output low level; no magnetic, show OFF state, output high level, dry reed pipe and magnetic induction distance within 1.5 cm, this distance ,insensitive or will not ; 2. The module DO output end can connect directly to microcontroller I/O port, triggered by single chip microcomputer can detect dry reed pipe status;it can detect the state of the dry reed by SCM 3. Modules DO output end connect the IN end of relay, can compose high power dry reed pipe switches, control high voltage directly. Package list: 4 x Reed module
