Reed Switch Sensor Module

Magnetic field sensing is one of essential things we do in industry.

• Sensors like Hall Effect, KY035 Sensors etc.
• they all sense the magnetic field and can give both analog or digital output accordingly.
• This Reed Switch sensor module is different as it works only as a switch and not as a measuring device.
• It has a glass enclosure filled with inert gas called Rhodium in which there are two ferrous elastic reeds which will close contact when a magnetic field is applied to it.
• Normally they are in open condition and will detect the presence of magnetic field and close the contacts.
• It can be used in applications like washing machines, automatic door opening devices, Electromagnetic relays etc.
• Reed Sensor Module Specifications Operating Voltage: 3.3V to 5V DC Output format: Digital switching output ( 0 and 1 ) LEDs indicating output and power Small, cheap and easily available LM393 Comparator IC onboard Product Using the Reed Switch sensor module with a microcontroller is very easy.
• Connect the Digital Output pin of the module to the Digital pin of Microcontroller.
• Connect VCC and GND pins to 5V and GND pins of Microcontroller.
• When the Reed Switch sensor detects the magnetic field, it closes the circuit and the digital pin of the module that is connected to the LM393 IC goes high.
• Package Contents 1× Reed sensor module.
