Ky025 Reed Switch Module

Reed Switch is a sensor that closes the circuit in presence of the magnetic field. It is a passive electronic switching component used to control the flow of electricity in a circuit. It contains a glass envelop in which two ferrous elastic reeds are enclosed in it with an inert gas called rhodium. Normally both of them are apart but when the magnetic field approaches the sensor, both reeds will come together hence completing the circuit. They can be used to detect whether a washing machine, refrigerator, or photocopier door is open or closed, Electromagnetic relays, weighing devices level meters etc. You can use it with Arduino, Raspberry Pi, PIC etc. microcontrollers in your DIY electronic projects for above mentioned applications. It is a Switch Module which means you don’t have to worry about converting the analog input to the digital input as it has a LM393 comparator IC onboard to convert it to digital signal. You can also check out the Reed Switch if you don’t want a module and want output for your other projects.
