3.3V-5V Magnetic Detect Sensor Module Digital Switch Output Magnetron MagSwitch

Description

3.3V-5V Magnetic Detect Sensor Module Digital Switch Output Magnetron MagSwitch
Product information
Uses:
PBX, photocopiers, washing machines, refrigerators , cameras, Xiaoduwangui , door , window magnetic , electromagnetic relays, electronic weighing, level meter , gas meter , water meter , etc. have been well used.
Module Features :
1. imported normally open reed
2. the comparator output signal is clean, good waveform , driving ability , more than 15mA.
3. the working voltage of 3.3V-5V
4. the output format : digital switching outputs ( 0 and 1 )
5. a fixed bolt holes for easy installation
6. PCB Size : 3.2cm x 1.4cm
7. using a wide voltage LM393 comparator
Module for use:
1. Reed needs and with the use of magnets in magnetic induction to a certain time, will form a conduction state , the module output low, when there is no magnetic force , was disconnected state , the output high , reed and sensing distance beyond the magnet within 1.5cm of insensitivity or may no trigger phenomenon ;
2. module DO output can be MCU I / O port is directly connected through the microcontroller can detect dry reed pipe trigger state ;
3. output and relay module DO IN terminal connected to form high-power reed switches, high voltage direct control .
Note:
The power supply can't be reversed polarity,otherwise, the chip will be burnt. When the signal indicator ON,output low voltage, when the iadicator OFF, output high voltage(is close the power supply voltage)
Package Include:
1 x Reed Sensor Module
